Help would be good i dont know how to do this

Mila [183]

$\frac{x^2-4x-32}{x^2+7x+12}=\frac{x^2+4x-8x-32}{x^2+4x+3x+12}=\frac{x(x+4)-8(x+4)}{x(x+4)+3(x+4)}=\\\frac{(x+4)(x-8)}{(x+4)(x+3)}=\frac{x-8}{x+3}$

Step-by-step explanation:

Step 1: Define

35 + 0.8x = 43 - 7x

Step 2: Solve for x

[Addition Property of Equality] Add 7x on both sides: 35 + 7.8x = 43
[Subtraction Property of Equality] Subtract 35 on both sides: 7.8x = 8
[Division Property of Equality] Divide 7.8 on both sides: x = 1.02564

Show how to make a ten to solve 3 - 7

Marta_Voda [28]

The 3 is a positive integer and the 7 is a negative integer so you would do "KFC" also known as (Keep, Flip, and Change)

3
("Keep" the 3 positive)
-
("Flip"the minus sign into a plus sign)

-7
("Change" the negative sign into a positive sign)

So therefore, you would have:

3 + 7, which equals 10
