Could you add the answer choices? It would be much easier to help you xD Thanks!!
Step-by-step explanation:
f(1) = 7
for n = 1
f(2) = f(2 - 1) + 2 = f(1) + 2 = 7 + 2 = 9
f(3) = f(3 - 1) + 2 = f(2) + 2 = 9 + 2 = 11
f(4) = f(4 - 1) + 2 = f(3) + 2 = 11 + 2 = 13
Answer:
A
Step-by-step explanation:
Answer:
<h2>A. 30(3 + 2)</h2>
Step-by-step explanation:
90 + 60
90 = 2 · 3 · 3 · 5
60 = 2 · 2 · 3 · 5
GCF(90, 60) = 2 · 3 · 5 = 30
90 = 30 · 3
60 = 30 · 2
The distributive property <em>a(b + c) = ab + ac</em>
90 + 60 = 30 · 3 + 30 · 2 = 30 · (3 + 2)
