Answer:
If you are trying to simplify the expression, the answer is -14x^2+8x-37
Step-by-step explanation:
First, keep removing the parentheses.
(x-1)(2-x)+(x^2+5)(x-7) -x^2(x+6)
Next, try expanding the expression.
3x - x^2 - 2+ (x^2+5)(x-7)-x^2(x+6
3x-x^2-2+x^3-7x^2+5x-35-x^2(x+6
3x-x^2-2x^3-7x^2+5x-35-x^3-6x^2
Finally, simplify the expression.
-14x^2 8x-37

I’m doing a percent equation problem and the question is blank % of $50 =$35 help me plzzzz
Answer:
70
Step-by-step explanation:
blank % of $50 =$35
Let us take x in place of blank.
x % of $50 =$35
x/100 * 50 = 35
x/2 = 35
x = 35*2
x = 70
Therefore, 70% of $50 =$35

D)
f(x) = -x2 - 2x + 15
find the midpoint of joining 4 - 5 and 8 - 3
Answer:
(6, - 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (8, - 3) , then
midpoint = ([tex]\frac{4+8}{2}[/tex], [tex]\frac{-5-3}{2}[/tex] ) = ([tex]\frac{12}{2}[/tex], [tex]\frac{-8}{2}[/tex] ) = (6, - 4 )

Which expression is equivalent to 8x - 12y + 32?
A. 16(0.5x 4y +32)
B. 16(0.5x - 0.75y + 32)
C. 16(0.5x - 0.75y + 2)
D. 16(0.5x + 4y +2)
Answer:
It's the third
16(0.5x - 0.75y +2)
Step-by-step explanation:
You just divide everything by 16
8x/16= 1/2x=0.5x
-12y/16 = -3/4x=-0.75x
32/16=2

Sorry forgot to post the problem here it is
Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55
