Answer:
x = 5
y = 23
Step-by-step explanation:
32x - 70 = 90
32x = 160
x = 5
16y + 92 = 13y + 161
3y = 69
y = 23
Answer:
(x + 3)(x + 7)
Step-by-step explanation:
Given
x² + 10x + 21
Consider the factors of the constant term (+ 21) which sum to give the coefficient of the x- term (+ 10)
The factors are + 3 and + 7, since
3 × 7 = 21 and 3 + 7 = 10, hence
x² + 10x + 21 = (x + 3)(x + 7)
9(n+7) = 18(n+1)
9n + 63 = 18n + 18
9n = 45
n = 5
answer
n = 5
