Evaluate the expression 5(7 − 4)2 ÷ 3 + 11.

5(3)2÷3+11

=(15)2÷3+11

=30÷3+11

=10+11

=21

=31

if you use pemdas, or parentheses, exponents, multiplication, division, addition, then subtraction, you can solve it like this:

5(7-4)2/3+11 solve the parentheses first, so 7-4=3

5(3)2/3+11 then move onto the next thing, multiplication (since there's no exponents)

(15)2/3+11 because 5*3 is 15

30/3+11 because 15 times 2 is 30

10+11 since 30/3 is 10

the answer is 21 since 10+11 is 21!

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
