Answer:

x = (+ - ) 9

Step-by-step explanation:

x^2 = 81

u know how u can sometimes cancel something out by doing the opposite.

This is one of those times as well. the opposite of ^2 = square root.

so if we take the square root of both sides, this will cancel out the^2 on the left side.

sqrt (x^2) = sqrt(81)

x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.

G(x)=3x^2-2x+7/2x+5 <br> find g(-1)
KengaRu [80]

Answer:

g(- 1) = 4

Step-by-step explanation:

To evaluate g(- 1) substitute x = - 1 into g(x)

g(- 1) = \frac{3(-1)^2-2(-1)+7}{2(-1)+5} = \frac{3+2+7}{-2+5} = \frac{12}{3} = 4
