Question

Which choice is equivalent to the expression below?

Answer 1

Answer:

C

Step-by-step explanation:

$3 \sqrt{5} + 8 \sqrt{5} = 11 \sqrt{5}$

Since they're all by the square root of 5, choice A and D are not correct.

Instead of multiplying 3 and 8, they should be added to eachother.

The answer is C
