Answer:
(r - 8)(r - 7)
Step-by-step explanation:
Consider the factors of the constant term (56) which sum to give the coefficient of the r- term (- 15)
The factors are - 8 and - 7, hence
r² - 15r + 56 = (r - 8)(r - 7) ← in factored form
Answer:
9
Step-by-step explanation:
Because 9 times 8 is 72. Hope this helps
Answer:
r = 6.08220
Step-by-step explanation:
to solve this is very simple and straight forward, you just have to evaluate the cube root of 225 to get the value of r.
solution
r^3=225
r = ∛225 it cannot be reduced because it is already in its simplest form.
r = 6.08220
Answer: B. 15
