Simplify the expression 4(5 - 2)2 – 7.

17

Step-by-step explanation:

Remember to solve by the order by operations, or PEMDAS. PEMDAS says that when simplifying an expression, you need to solve parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right) in that order.

1) Knowing this, start by solving what's in the parentheses:

2) Then - still following the order of operations - multiply the 4, 3, and 2 together.

3) Finally, subtract 7 from 24.

Therefore, 17 is the answer.

27.6

Step-by-step explanation: i think this is correct but you basically just do 228 X 0.121 (the percent in decimal form) and you get 27.58800 and when rounded that becomes 27.6 sorry if it’s incorrect hope this helped :)
