Answer: 116.12
Explanation:
13 x 7 = 91
13 - 5 = 8
8 / 2 = 4
3.14(4)^2 = 50.24
50.24 / 2 = 25.12
91 + 25.12 = 116.12

The answer is

.
Before we rationalize the denominator, we must simplify the numerator and denominator. We evaluate the square root on the top, and combine like terms on the bottom:

To rationalize the denominator, we multiply by the conjugate. The conjugate is found by making the imaginary term of the complex number, the i part, the opposite sign. The conjugate of -2-i is -2+i:
Set up an equation 20=k(0.4)....to find k divide 20 by 0.4
I couldn’t see the whole picture so I’m not sure if I could really help I’m sorry maybe next time
