-6x - 29 + 7x = 8 and -8x + 6x - 13 = 33
Mumz [18]
First equation:
-6x-29+7x=8
Combine like terms
-6+7=1
1x-29=8
Add 29 to both sides
1x=37
Divide both sides by 1
x=37

Second equation:
-8x+6x-13=33
Combine like terms
-8+6=-2
-2x-13=33
Add 13 on both sides
-2x=46
Divide both sides by -2
x=-23

What is the quotient (125 – 8x3) ÷ (25 + 10x + 4x2)?<br> –2x + 5<br> 2x – 5<br> –2x – 5<br> 2x + 5
Anit [1.1K]

For this case we have the following expression:

\frac{125-8x^3}{25+10x+4x^2}

Factoring the numerator we have:

\frac{-(2x+5)(4x^2+10x+25)}{25+10x+4x^2}

Rewriting the denominator we have:

\frac{-(2x+5)(4x^2+10x+25)}{4x^2+10x+25}

Canceling similar terms we have:

-(2x+5)

-2x-5

Answer:

The quotient of the division is given by:

-2x-5
