Answer:

x = -2

Step-by-step explanation:

$f(x)=x^{2}+18x+7$

$g(x)=-3x^{2}+2x-9$

$f(x)=g(x)$

$\implies x^2 +18x+7=-3x^2 +2x-9$

$\implies 4x^2 +16x+16=0$

$\implies x^2 +4x+4=0$

$\implies (x+2)^2=0$

$\implies x+2=0$

$\implies x=-2$

7n - 4 (8n+4) = 159

Romashka [77]

Answer:

n = -7

Step-by-step explanation:

Use distributive property:

7n - 32n - 16 = 159

Combine like terms

-25n - 16 = 159

Add 16 to both sides to isolate variable n

-25n = 175

Divide both sides by -25 to isolate variable n

n = -7

Check your work:

7(-7) - 32(-7) - 16 = 159

-49 + 224 - 16 = 159

159 = 159
