Question

12+[15+2(3X5) ] *5 PS DO IT FOR ME

Answer 1

57

Explanation:

We know that parentheses come first in the order of operations. Therefore, we will first evaluate (3 × 5).

3 × 5 = 15

↓ substituting this value back in for the parentheses

`12+[15+2(15)]`

Next, we will deal within the brackets, which act like parentheses. Multiplication comes before addition, so we will execute 2(15) first.

2(15) = 2 × 15 = 30

↓ substituting this value back in

`12+[15+30]`

Now, executing the addition:

15 + 30 = 45

↓ substituting this value back in for the brackets

`12 + 45`

Finally, all there is to do is execute the addition.

12 + 45 = 57

`\boxed{57}`
