<h2>
Step-by-step explanation: </h2>
The equation is
5x² + X -7
Putting X as 6 we get
=5(6)²+6−7
=(5)(36)+6−7
=180+6−7
=186−7
=179
Answer:
149
Step-by-step explanation:
5 to the second power is 25, because you do 5x5. Then you multiply 25 by x, which is 6, and get 150. Then you add 6 to 150, which is 156, and subtract seven. Also the answer is 149.

Step-by-step explanation:
The radius was divided by 2.
31.4 = 2pi * r
31.4/2pi = 15.7/pi
15.7 = 2pi * r
15.7/2pi = 7.85/pi
(7.85/pi) / (15.7/pi) = 1/2
