Answer:
Step-by-step explanation:
the answer is 45
(4a+6b)×(a-b)
=4a(a-b)+6b(a-b)
=4a^2-4ab+6ab-6b^2
=4a^2+2ab-6b^2
Answer:
310 in²
Step-by-step explanation:
The general formula for the surface area of a prism is:
SA = 2ab + 2ac + 2bc, where 'a', 'b' and 'c' are the measures of the sides. In this case the lengths are 4 in, 5 in and 15 in.
a = 4 in
b = 5 in
c = 15 in
SA = 2(4*5) + 2(4*15) + 2(5*15)
SA = 40 + 120 + 150 = 310 in²
The answer you are looking for is C, that is the best option that i see by looking at the graph and your answer choices. hope this helps and sorry about the wait for an answer.
Step-by-step Answer::
"Each month, the balance in the account increases by 0.25%"
means F(n)=F(n-1)*1.0025
"Elaine deposited $50 into a bank account."
means F(0) = 50
So a recursive definition is
F(n) = F(n-1)*1.0025 for n=1,2,3,4... and F(0)=50
Symbols used in the actual answer choices may differ, but with the same principle.
