Answer:
Step-by-step explanation:
Given the expression
<u>Expand and simplify the expression</u>
Expand 4(2x + 7) = 8x + 28
Expand -3(x + 5) = -3x - 15
Group like terms
Add similar elements: 8x - 3x = 5x
Simplify
Therefore, we conclude that:
If you know your doubles, then it should be easy to go from 4 + 4 = 8 to 4 + 5 = 9.

100/52=?
?x2600=5000
r = 45 m.
pi r^2 = 6358.5
r^2 = 6358.5 / pi
r = √(6358.5 / pi)
= 44.989 m
