Question

Factor the following expression using the GCF: 15st + 20t.

A) 5t(3s + 4)
B) 5t(15s + 20)
C) 15st(3s + 4)
D) 5ts(15 + 20)

Answer 1

To factor the expression 15st + 20t, the GCF is 5t, resulting in the factored form of 5t(3s + 4), which corresponds to option A.

Step-by-step explanation:

To factor the expression 15st + 20t using the GCF (Greatest Common Factor), we first need to identify the common factors of both terms. We notice that 5 and t are common to both terms. So, we can factor those out:

15st + 20t = 5t(3s) + 5t(4) = 5t(3s + 4).

Thus, the factored form of the expression using the GCF is 5t(3s + 4), which corresponds to option A.
