True or False
Q1) If x = 2 and y=1, the value of -8x³y⁴/7 is -64/7 *
Q2) x/4 + x/6 - x/2 = 3/4, The value of x= -9 *
Q3) The Factors of 1-2ab-(a²+b²) are (1+a-b)(1+a+b) *
Q4) In the point (2,3), 3 denotes the abscissa *
Q5) The points (7,9) and (9,7) represent the same point *
Q6) There are three perfect cubes between 1 to 100. *
Q7) The cube of an even natural number 12 is 1728 *
Q8) The value of (a+1)(a-1)(a²+1) is (a⁴ -1) *
Q9) The sum of areas of two squares with sides 5a and 5b is 25(a+b)(a-b) *
Q10) abc + bca +cba is a monomial *
Will mark and many points
Step-by-step explanation:
Q1)
for x = 2, y = 1
-8x³y⁴/7 = -64/7
-8×2³×1⁴/7 = -8×8×1/7 = -64/7
true
Q2)
x/4 + x/6 - x/2 = 3/4
is x = -9 ?
bringing everything to 1/12 ...
3x/12 + 2x/12 - 6x/12 = 3×3/12
-x/12 = 9/12
-x = 9
x = -9
true
Q3)
can
1 - 2ab - (a² + b²) = 1 - 2ab - a² - b² be factored as
(1 + a - b)(1 + a + b)
let's multiply
(1 + a - b)(1 + a + b) =
= 1 + a + b + a + a² + ab - b - ab - b² =
= 1 + 2a + a² - b²
this is NOT the same as
1 - 2ab - a² - b²
false
Q4)
The horizontal distance of a point from the y-axis is called abscissa or x coordinate of the point.
3 is the y coordinate of (2, 3) and not the x coordinate.
false
Q5)
(7, 9) and (9, 7)
the x coordinates are different, and the y coordinate are different. so, they are definitely NOT the same point.
this would be like saying 5 hours and 3 minutes is the same as 3 hours and 5 minutes.
false
Q6)
now, this is tricky. there are 4 perfect cubes between 1 and 100 :
1×1×1 = 1
2×2×2 = 8
3×3×3 = 27
4×4×4 = 64
did your teacher mean "exactly 3 perfect cubes" ? because, since there are 4, there are also 3, of course (and 2, and 1).
and did "between 1 and 100" mean including the numbers 1 and 100, or excluding the numbers 1 and 100 ?
so, if excluding 1 and 100, then it is true.
if including 1 and 100 and asking for exactly 3, then it is false.
if including 1 and 100 and truly only asking for 3, then it is true.
Q7)
12³ = 12×12×12 = 144×12 = 1728
true
Q8)
(a+1)(a-1)(a²+1) = (a⁴ -1) ?
let's multiply
(a² + a - a - 1)(a² + 1) = (a²-1)(a²+1) = a⁴ - a² + a² - 1 = a⁴-1
true
Q9)
the areas of the 2 squares are
25a² and 25b²
the sum is
25a² + 25b² = 25(a² + b²)
but
25(a+b)(a-b) = 25(a² - b²)
this is NOT the same.
false
Q10)
abc + bca + cba
a monomial is, roughly speaking, a polynomial which has only one term.
but the given expression has 3 terms.
false

Answer:
11
Step-by-step explanation:
You replace all the x with 12 when its f(12). if its f(3) you would replace all the x with 3.
So,
f(12)=2/3(12)+3
f(12)=8+3
f(12)=11
In Jack's basement, there's an area that is 6 feet long and 5 , 5 feet wide for the kids to play ping pong. In Mike's basement, there is an area that is 12 feet long and 5 Ź feet wide to play ping pong and other games. How many times larger is the area of Mike's basement? Draw a model on the grid paper, and show your
Mike's area basement is 2 times larger than Jack basement area.
Area of a rectanglearea = lw
where
l = length
w = width
Therefore,
Jack's basement area:
length = 6 ft
width = 5 ft
area = 6 × 5 = 30 ft²Mike's basement area;
length = 12 feet
width = 5 feet
area = 12 × 5 = 60 ft²Therefore, Mike's area basement is 2 times larger than Jack basement area.

The length of a rectangle is 2 centimeters less than its width. What are the dimensions of the rectangle if its area is 168 square centimeters
Given :
The length of a rectangle is 2 cm less than its width.Area of the rectangle is 168 cm²To Find :
The dimensions of the rectangle.Solution :
Let us assume the length of the rectangle as x cm and therefore the breadth will be (x + 2) cmWe know that,
[tex] \purple{ \boxed{\quad \bf Length \times Width = Area_{(rectangle)}}}[/tex]
Now, Putting the values in the formula :
[tex]{ \qquad \sf { \dashrightarrow{ x(x + 2)= 168 {cm}^{2} }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}^{2} + 2x= 168 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}^{2} + 2x - 168=0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}^{2} - 12x + 14x - 168 = 0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}(x - 12) + 14(x - 12) = 0 }}}[/tex]

[tex]{ \qquad \sf { \dashrightarrow{ ({x} - 12) = 0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x} = 12 }}}[/tex]
Whether x = (–14) or 12The length of the rectangle can never be negative so the length must be 12 cm .
Therefore, Width = (12 + 2) = 14 cm .

Can you still use the triangle sum Theorem even if a triangle is not in 180 degrees?
Hi!
You cannot.
This is because ALL triangles MUST have 180 degrees, so if it doesn't it's not even a triangle. Therefore you cannot use it because, well, it's not a triangle.
Answer:
The sum of interior angles is 180 degrees (Triangle Angle Sum Theorem). All interior angles of a triangle are more than 0° but less than 180°.

Combine the fractions on the left side:
9/(x + 2) + 2/(x - 2) = 1
9 (x - 2) / ((x + 2) (x - 2)) + 2 (x + 2) / ((x + 2) (x - 2)) = 1
(9x - 18) / ((x + 2) (x - 2)) + (2x + 4) / ((x + 2) (x - 2)) = 1
(9x - 18 + 2x + 4) / ((x + 2) (x - 2)) = 1
(11x - 14) / ((x + 2) (x - 2)) = 1
Recall the difference of squares identity,
a² - b² = (a + b) (a - b)
which lets us simplify the denominator on the left side as
(11x - 14) / (x² - 4) = 1
For any real numbers a and b, if a/b = 1, then a = b. This means
11x - 14 = x² - 4
which we can rearrange as
x² - 11x + 10 = 0
Factorize the left side:
(x - 10) (x - 1) = 0
Then
x - 10 = 0 or x - 1 = 0
x = 10 or x = 1

Given the following arithmetic sequence; starting with 107, which term has a value of -61?
107, 101, 95...-61
(show steps pls)
Answer:
Step-by-step explanation:
The pattern of this sequence is : From a term, we minus 6 to get to the next term
107 - 6 = 101
101 - 6 = 95
So on and so on.
The difference between 107 and -61 is : 107 - (-61) = 168
Everytime we go to the next term, we get 6 units closer to -61
So, -61 will be the 168 : 6 = 28th term of this arithmetic sequence.
