Answer:

B -9(9x-3)

Step-by-step explanation:

b/c -9(9x-3) means -9×9x-(-3)

= -81x+27

if you say why -(-3) is +27, I will say b/c negative times negetive it give us positive. and if you they why we don't add -81x and 27, I will say b/c they are not like terms.

like terms : are terms with the same variable and same exponent.

example:2x and 3x,5xy and 9yx and etc....

if it helpful ❤❤

9(x + 2) = 5 - 2x - 1)
irina1246 [14]

Answer:

-1

Step-by-step explanation:

9(x+2)=5−2(x−1)

9x+18=5−2(x−1)

9x+18=5−2x+2

9x+18=7−2x

9x+18+2x=7

11x+18=7

11x=7−18

11x=−11

x=  11 /−11

​x=-1

Solve for x. 5x^2 – 45 = 0
mamaluj [8]

5x^2-45=0

<em>*Add 45 to both sides*</em>

5x^2=45

<em>*Divide both sides by 5*</em>

x^2=9

<em>*Take the square root of both sides*</em>

x=+/-9

Hope this helps!!
