Answer 2

Answer:

21.16

Explanation:

7.4 with an exponent of 2= 54.76

6.4 with an exponent of 2=40.96

8.9 with an exponent of 2=79.21

54.76- 40.96= 13.8 divided by 79.21=0.17(rounded to the hundredths place)

8.9+0.17=9.07 multiplied by 2.2= 19.95 (rounded to the hundredths place)

1.1 with an exponent of 2= 1.21 plus 19.95= 21.16
