Which is a solution to (x - 3)(x + 9) = -27? ox=-9 ox= -3 ox= 0 ox= 6

x = 0 or x = -6

Step-by-step explanation:

Solve for x:

(x - 3) (x + 9) = -27

Expand out terms of the left hand side:

x^2 + 6 x - 27 = -27

Add 27 to both sides:

x^2 + 6 x = 0

Factor x from the left hand side:

x (x + 6) = 0

Split into two equations:

x = 0 or x + 6 = 0

Subtract 6 from both sides:

 x = 0 or x = -6

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
