Answer:
x = - 7, x = - 1
Step-by-step explanation:
To find the zeros let f(x) = 0 , that is
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = + 7 and 7 + 1 = + 8 , then
x² + 8x + 7 = 0
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1
The correct answer would be A. C = 0.69p.
This is the correct answer because the total cost of the bananas should equal 0.69 times each pound bought.
Hope this helped!
Answer:
n = 5/√7
Step-by-step explanation:

5√7 = 7n
7n = 5√7
n = 5√7/7
n = 5/√7
