Simplify I need help with this math homework

A.

Step-by-step explanation:

Simplify the square root to 60 times 4. Do the square root 4 then it is 2 times the square root of 60. You can simplify 60 to 4 times 15. the square root of 4 is 2 and multiply 2 times 2 which is 4. Then you final answer is 4 times the square root of 15. Hope this helps!

Step-by-step explanation:

Find the prime factorization of 240.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
