Question

Which expression has a value that is equal to the given expression when n = 8? 2n + 10 A. 3n

B. 10n + 2
C. n² + 5
D. 2(n+5)

Answer 1

D. 2(n+5)

Explanation:

I took the test (5.02 quiz)

Answer 2

D.

Explanation:

2n + 10

When n = 8 we have

2*8 + 10

= 16 + 10

= 26.

When n = 8:

2(n + 5)

= 2(8 + 5)

= 2*13

= 26.

So it's D.
