1. Find the product of (n - 5) and (n + 5).
n²-25
Explanation:Expand the polynomial using the FOIL method. (A handy way to remember how to multiply two binomials. It stands for "First, Outer, Inner, Last")
Answer:
n² - 25
Step-by-step explanation:
(n - 5)(n + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
n(n + 5) - 5(n + 5) ← distribute parenthesis
= n² + 5n - 5n - 25 ← collect like terms
= n² - 25
If 24 muffins cost 46$ how much does 1 muffin cost
Answer:
1,916666666666667$Step-by-step explanation:
If 24 muffins cost 46$ how much does 1 muffin cost?
46 : 24 =
1,916666666666667$
(the total cost is 46$ or 48? are you sure?)
Hey there!
It costs about $46 for 24 muffins, so in order to find out the total cost for 1 muffin you have to DIVIDE 46 from 24 or 24 from 46.
So, lets first divide 46 from 24
46 / 24
= 46 ÷ 24
= 46 ÷ 2 / 24 ÷ 2
= 23 / 12
= 1.916667
≈ 1.92
Therefore, your answer is: $1.92

7. How many different 7-letter combinations can be
formed from the word GEOMETRY if repetitions are
not permitted?
A4 ore
Explanation:
There are 8 letters in the word "GEOMETRY".
Use the nPr permutation formula with n = 8 and r = 7 and you'll find that 8P7 = 40320.
Or you can compute it like this 8*7*6*5*4*3*2 = 40320
This would be the answer if we could tell the E's apart.
However, we cannot tell the E's apart, so we have to divide by 2 to correct for the double-counting.
There are 40320/2 = 20160 different seven letter combinations possible.

Drag each number to show whether or not it is a solution to the inequality shown.
Inequality: 20≥5+3x
Answer:
solutions: -15, 4 3/4
not solutions: 10 2/3 and 129
Step-by-step explanation:
Let's solve the inequality first
[tex]20 \geqslant 5 + 3x \\ 20 - 5 \geqslant 3x \\ 15 \geqslant 3x \\ 5 \geqslant x[/tex]
so solution set must contain all the values that are less than equal to 5.
-15 and 4 3/4 are less than 5
so these are solutions.
129 and 10 2/3 are bigger than 5. That means these are not solutions.

Find the unknown sizes of angles
Answer:
R=50 b=130 a=135
Step-by-step explanation:
Sum of Internal angles = 180
R= 180-85-45 = 50
missing interior angle R = 50
If a side of a triangle is produced, then the exterior angle that is formed is equal to the sum of the two interior opposite angles.
P+Q = 85+45= 130 b=130
P+R = 85+50 = 135 a=135
To solve this problem, we would have to add the sum of angles in a triangle and then find the missing side. Furthermore, value of R, a and b are 50°, 135° and 130° respectively.
Data;
P = 85°Q = 45°a = ?b = ?Sum of Angles in a TriangleThe sum of angles in a triangle is equal to 180° and we can find the missing side on R.
[tex]P+Q+R = 180^0\\85^0+45^0+R = 180^0\\130^0+R=180^0\\R = 180 - 130 \\R = 50^0[/tex]
Since we know the value of R and Q, we can proceed to find a and b.
[tex]Q+ a = 180\\[/tex]
The reason behind this is that the sum of angles on a straight line is equal to 180^0
[tex]45+a = 180 \\a = 180 - 45 \\a = 135^0[/tex]
Now let's find the value of b
[tex]R + b = 180\\R = 50^0\\50 + b = 180\\b = 180 - 50 \\b = 130[/tex]
From the calcuations above, the value of R, a and b are 50°, 135° and 130° respectively.

Each pair of figures is similar. Find the missing side.
Answer:
The missing side is X=4
Step-by-step explanation:
Since the triangles are similar to eachother, they will have the same ratio.
One way to solve is dividing 8 by 2. Since 12 divided by 2 is 6,
we can expect 8 divided by 2 to be the missing side we are looking for.
Hope that helps!
Answer:
x = 4
Step-by-step explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{x}{8}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )
12x = 48 ( divide both sides by 12 )
x = 4
A game of "Doubles-Doubles" is played with two dice. Whenever a player rolls two dice and both die show the same number, the roll counts as a double. If a player rolls doubles, the player earns 5 points and gets another roll. If the player rolls doubles again, the player earns 5 more points. Whenever the player rolls the dice and does not roll a double, they lose points. How many points should the player lose for not rolling doubles in order to make this a fair game? Three-fifths 1 5 Three-fifths.
Using the expected value of a discrete distribution, it is found that the amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.
What is the expected value of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
In this problem, considering 6 out of 6^2 = 36 outcomes are doubles, we have that the distribution is:
P(X = 5) = 1/6.
P(X = x) = 5/6.
A fair game means that the expected value is of 0, hence:
[tex]5\frac{1}{6} - \frac{5x}{6} = 0[/tex]
[tex]\frac{5x}{6} = \frac{5}{6}[/tex]
[tex]x = 1[/tex]

Answer:
∠TVX = 49°
x = 52°
x = 57.5°
BC = 6 cm
Step-by-step explanation:
Question 1
Angle at the Centre Theorem:
∠UTV = 1/2 ∠UOV = 134 ÷ 2 = 67°
Angles around a point add up to 360°
⇒ interior angle of ∠UOV = 360 - 134 = 226°
The sum of interior angles of a non-cyclic quadrilateral is 360°
⇒ ∠OVT = 360 - 26 - 226 - 67 = 41°
As WVX is a tangent, it forms a right angle with the radius (OV)
⇒ ∠TVX = 90 - 41 = 49°
Question 2
Angles on a straight line add up to 180°
The angle between a tangent and a chord is equal to the angle in the alternate segment.
Therefore ∠x = 180 - 68 - 60 = 52°
Question 3
As CD is a tangent ⇒ OC = radius ⇒ ∠OCD = 90°
The sum of interior angles of a triangle is 180°
⇒ ∠COD = 180 - 90 - 25 = 65°
As ∠COD =∠AOB then ∠AOB = 65°
As OB and OA are radii, triangle AOB is an isosceles triangle. Therefore ∠OBA = ∠OAB
Therefore x = (180 - 65) ÷ 2 = 57.5°
Question 4
As BC is the tangent to the smaller circle, OA is perpendicular to BC.
Therefore, triangle OAB is a right triangle with hypotenuse 5 cm.
Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs, and c is the hypotenuse of a right triangle):
⇒ AB² + 4² = 5²
⇒ AB = √(5² - 4²) = 3
⇒ BC = 2 x AB = 3 x 2 = 6 cm

Given the polynomial 2x3 18x2 − 18x − 162, what is the value of the constant 'k' in the factored form? 2x3 18x2 − 18x − 162 = 2(x k)(x − k)(x 9) 3 6 9 18.
The value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.
What is polynomial equation?Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).
The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.
The given polynomial equation in the problem is,
[tex]2x^3 +18x^2 - 18x - 162[/tex]
The factor of the polynomial equation are given as,
[tex]2(x+ k)(x - k)(x +9)[/tex]
First find out the factors to compare and find the value of k.The above equation has the unknown variable x and the highest power of this unknown variable is 3.
Take out the highest common factor 2, which can divide each term of the above equation (2, 18, -18, -162). Thus,
[tex]2(x+ k)(x - k)(x +9)=2(x^3 +9x^2 - 9x - 81)[/tex]
Take out the highest common factor to make the groups as,
[tex]2(x+ k)(x - k)(x +9)=2(x^2( x+9) - 9(x + 9))\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 9)\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 3^2)[/tex]
Use the property of difference of the square for the (x²-3²) term as,
[tex]2(x+ k)(x - k)(x +9)=2( x+9) (x+3)(x-3)\\2(x+ k)(x - k)(x +9)=2 (x+3)(x-3)( x+9)[/tex]
On comparing the two equation, we get the value of k as 3. Thus, the value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.
