If dimensions are multiplied by 3 then area is multiplied by 3^2
Answer:
(x - 3)(x - 9)
Step-by-step explanation:
Consider the factors of the constant term (+ 27) which sum to give the coefficient of the x- term (- 12)
The factors are - 3 and - 9, hence
x² - 12x + 27 = (x - 3)(x - 9 )
If x - 7 = -13, we need to get x by itself to solve this equation. To get x by itself, we can add 7 to each side (that way x will be by itself, and only on one side of the equation).
x - 7 + 7 = -13 + 7
We can add 7 to each side without changing the quantity because we do it to BOTH sides.
x = -13 + 7
Since -13 + 7 is -6,
x = -6
