Suzie solves the equation below:
x2 + 4x - 12 = 2
(x - 2)(x + 6) = 2,
by setting x -2 = 0 and x + 6 = 0.
Her solutions are x = 2 and x = -6.
Is Suzie correct? Why or why not?
Answer:
Suzie's answers are incorrect.
Step-by-step explanation:
x^2+4x-12=2
+12 +12
x^2+4x=14
(if we put Suzie's answer in for x)-
2^2+4(2)=14
4+8=14
Suzie's first answer is incorrect (4+8=12)
Let's try the next one with Suzie's answer
(-6-2)(-6+6)=2
(-8)(0)=2
This answer is also incorrect. (-8*0=0)

Can yall find EB? Round the the nearest hundred. AD=8.98, AB=6.47. ABCD is a rectangle
Answer:
5.53408980773 or 5.534
Step-by-step explanation:
Let's take AD as a, AB as b and DB as c
a2+b2 =c2
(8.98)2 + (6.47) 2 =c2
80.6404 + 41.8609 =c2
The number 2 is square . take it like square
122.5049 =c2
[tex] \sqrt{c \: \: } = \sqrt{122.5049 } [/tex]
C=11.0681796155
this valse is DB but the question say EB so dividend by 2 because rectangle diagonal are equal
So EB =11.0681796155/2
EB =5.5340890773
A piece of wood is 0.9 metres long.
It is cut into three unequal pieces.
The first piece is 0.2 metres longer than the second piece.
The third piece is 23 hundredths of a metre shorter than the second piece.
How long is each piece of wood?
Answer:
The length of the first piece is 0.51 m
The length of the second piece is 0.31 m
The length of the third piece is 0.28 m
Step-by-step explanation:
The question is a simultaneous equation with word problem
The total length of the wood = 0.9 m
The number of pieces the wood is cut into = 3
The length of the first piece = 0.2 m + The length of the second piece
The length of the third piece = The length of the second piece - 0.23 m
Let "y" represent the length of the second piece, let "x" represent the length of the first piece, and let "z" represent the length of the third piece, we have;
x = 0.2 + y...(1)
z = y - 0.23...(2)
x + y + z = 0.9...(3)
Therefore, by substitution, we have;
0.2 + y + y + y - 0.23 = 0.9
3·y - 0.03 = 0.9
3·y = 0.9 + 0.03 = 0.93
y = 0.93/3 = 0.31
y = 0.31
The length of the second piece = y = 0.31 m
From equation (1), we have;
x = 0.2 + y = 0.2 + 0.31 = 0.51
x = 0.51
The length of the first piece = x = 0.51 m
From equation (2), we have;
z = y - 0.23
z = 0.51 - 0.23 = 0.28
z = 0.28
The length of the third piece = z = 0.28 m.

a 20% sugar syrup is mixed with 10% sugar syrup.The result is 600 g of 12% sugar syrup. How many grams of each syrup are in the mixture.
Answer:
120 grams of 20% sugar and 480 grams of 10% sugar
Step-by-step explanation:
The reason that the answer is what it is is because the total of the sugar syrup must be 600 grams. It is 12% which means that its 1/5 20% and 4/5 10% and if you divide 600 by 5 you get 120 therefore 120 grams of 20% sugar is correct and for the rest just subtract 120 from 600 the get the answer.
There are 120 g of 20% sugar syrup and 480 grams of 10% of sugar syrup.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
A 20% sugar syrup is mixed with 10% sugar syrup.
And, The result is 600 g of 12% sugar syrup.
Now,
It is 12% which means that its 1/5 of 20%.
Hence, Amount of sugar grams = 600 / 5
= 120 grams
And, It is 12% which means that its 4/5 of 10%.
Hence, Amount of sugar grams = 600 / (4/5)
= 480 grams

Dennis read 30% of his book on Tuesday and of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Answer:
1/2x
Step-by-step explanation:
Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Total pages of the book = x
Tuesday = 30%
= (30/100)x
= 3/10x
Wednesday = 1/5x
3/10x + 1/5x
= 3x+2x/10
= 5/10x
= 1/2x
what fractional part of the book did he have left to read after Wednesday
= x - 1/2x
= 2x-x/2
= x/2

Is x = 6 a solution to the equation x + 13 = 18?
O A. Yes, because 6 +13 = 18 is true.
O B. No, because 6 + 13 = 18 is true.
C. No, because 6 + 13 = 18 is not true.
D. Yes, because 6 + 13 = 18 is not true.
x = 6 is not a solution to the equation x + 13 = 18.
Hence, Option C) No, because 6 + 13 = 18 is not true. is the correct answer.
Is x = 6 a solution to the equation x + 13 = 18?Given the equation; x + 13 = 18.
We plug x = 6 into the equation
x + 13 = 18
6 + 13 ≠ 18
6 + 13 is not 18
x = 6 is not a solution to the equation x + 13 = 18.

Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. For how many years did he save this money?
Answer:
7 years.
Step-by-step explanation:
To find this, we need to find 2% of 2,000. To do this, we mulitply 2,000 by .02. This gets us 40. Now, we need to divide 280 by 40 to find the amount of years it took for Mike to get this money. When we do that, it gets us 7. That means Mike saved that money for 7 years.
The number of years that he saves this money will be 7 years.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The formula for interest is written as,
I = (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. Then the number of years is calculated as,
$280 = ($2,000 x 2 x T) / 100
$28,000 = $4,000 x T
T = $28,000 / $4,000
T = 7 years
The number of years that he saves this money will be 7 years.

Lines AB, CD, and LK intersect as shown in the diagram . Find M
the last one is the answer
The measurement of ∠ CSK = 110.2°
What is Parallel line?Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.
Given that Lines AB, CD, and LK intersects at R and S respectively,
m∠LRB = (3x - 2)° and m∠RSC = (2x - 5)
m∠LRB = m∠CSK → (Alternate exterior angles)
m∠CSK + m∠RSC = 180° → (Linear pair angles)
Therefore, m∠LRB + m∠RSC = 180°
(3x - 2)° + (2x - 5) = 180°
5x - 7 = 180°
5x = 187°
x = 37.4°
So, m∠CSK = (3x - 2)°
(3x - 2)° = 3*37.4 - 2
m∠CSK = 110.2°
Hence, The measurement of ∠ CSK = 110.2°

find the slope of the line
Answer:
slope: -2
Step-by-step explanation:
please help and show work
Answer:
see explanation
Step-by-step explanation:
(3)
The opposite sides of a parallelogram are congruent, so
6x = 3x + 15 ( subtract 3x from both sides )
3x = 15 ( divide both sides by 3 )
x = 5
and
2y - 10 = y + 5 ( subtract 5 from both sides )
y - 10 = 5 ( add 10 to both sides )
y = 15
Then x = 5 and y = 15
-------------------------------------------------------------------------
(4)
The diagonals of a parallelogram bisect each other, thus
y = 4x - 6 → (1)
9x - 25 = 2y → (2)
Substitute y = 4x - 6 into (2)
9x - 25 = 2(4x - 6)
9x - 25 = 8x - 12 ( subtract 8x from both sides )
x - 25 = - 12 ( add 25 to both sides )
x = 13
Substitute x = 13 into (1)
y = 4(13) - 6 = 52 - 6 = 46
Then x = 13 and y = 46

Which expressions are equal to
23 ?
Answer: The first option and the third option
Step-by-step explanation: You are not supposed to find something equivalent to the fraction, you have to divide the fraction.
13824 ÷ 8 = 1728
Then it is when you try to find a number equivalent to 1728. 12 to the power of 3 equals 1728
12×12=144
144×12=1728
12 to the power of 3 is equivalent to 1728
These are wrong: 2 to the power of three is unequivalent and so is 12 to the power of 6 and 6 to the power of 3
2 to the power of 6 is 64
2×2=4
4×2=8
8×2=16
16×2=32
32×2=64
3 to the power of 3 is 27
3×3=9
9×3=27
64 times 27 equals 1728 so it's equivalent and that means that our answers are A, the 1st option , and C, the 3rd option
The equivalent expression will be;
