Answer:
4(x + 5)(x - 3)
Step-by-step explanation:
Given
4x² + 8x - 60 ← factor out 4 from each term
= 4(x² + 2x - 15) ← factor the quadratic
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then
x² + 2x - 15 = (x + 5)(x - 3)
Then
4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form
Answer:
.58c
Step-by-step explanation:
Find 42% of c
.42c
Then subtract that from c
c - .42c
.58c
.58c is 42% less than c
To solve this problem, you’re going to take 5.5 and divide it by 1.375. In doing so, you will get a final answer of 4 pieces.
5.5 / 1.375 = 4
