Answer:
(x + 10)(x + 8)
Step-by-step explanation:
Given
x² + 18x + 80
Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)
The factors are + 10 and + 8 , since
10 × 8 = + 80 and 10 + 8 = + 18 , then
x² + 18x + 80 = (x + 10)(x + 8) ← in factored form
Answer: D.) 33.66
Steps:
First find discount
19.80x * 0.15
19.80(2) * 0.15
39.6 * 0.15
5.94
19.80x - 5.94
19.80(2) - 5.94
39.60 - 5.94
33.66
Answer:
x = 12.75
Step-by-step explanation:
10.2 : x = 0.8
x = 10.2 : 0.8
= 102/10 : 8/10
= 102/10 × 10/8
= 102/8
= 12.75
12x2=24 8x3=24 , so all you needed was to multiply the week until you got the same answer for both
