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

It's the third

16(0.5x - 0.75y +2)

Step-by-step explanation:

8x/16= 1/2x=0.5x

-12y/16 = -3/4x=-0.75x

32/16=2

Answers

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

I’m doing a percent equation problem and the question is blank % of $50 =$35 help me plzzzz

Answers

Answer:

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

find the midpoint of joining 4 - 5 and 8 - 3​

Answers

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 )
