Can anyone help? thanks!

Answer 1

175

Explanation:

Since we have 7ca^2 and since we know a = 5 and c = 1, we can just plug in these values for a and c and follow the order of operations:

`7ca^2\\7(1)(5)^2\\7(1)(25)\\7*25=175`

Answer 2

Answer: 175

Explanation:

7 x 1 x 5^2

7 x 1 x 25

7 x 25

175
