➷ Just substitute the given value into anywhere you see the term x:

2 x 4^2 + 12

Follow the PEMDAS rule:

(calculate the exponential first)

4^2 = 16

Now we have:

2 x 16 + 12

(now the multiplication needs to be calculated)

16 x 2 = 32

Now we have:

32 + 12

Add them together to get the answer:

44 <== this is the answer

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
