Question

On your pattern, what would y be when x = 132

What is the first step in simplifying the expression
(9-7x3+4)²?
(A) square 4
(B) subtract 7 from 9
[C] add 3 and 4
[D] multiply 7 by 3
​

Answer 1

D

Explanation:

The expression is
`(9-7*3+4)^2`

We can follow the rule of "PEMDAS" here.

PEMDAS = Parenthesis, Exponents, Multiply, Divide, Add, Subtract

So, we first need to deal with Parenthesis. Next,

There aren't any exponents, so we deal with Multiplication of 7 and 3.

Then addition/subtraction.

Hence, the first step, from the answer choices, would be D, multiply 7 and 3
