Answer:
C. 300
Step-by-step explanation:
EFG and EG is the total distance around the circle
EFG + EG = 360 degrees
EFG + 60 = 360
Subtract 60 from each side
EFG +60-60 = 360-60
EFG = 300
Step-by-step explanation:
the area of this rectangle is
(10 + 2x)(8 + 2x) = 168
80 + 20x + 16x + 4x² = 168
4x² + 36x = 88
because for the whole length you need to add x twice (left and right). the same for the width (top and bottom).
<span>2x+12+6x+1-x
You are adding up 2x and 6x and deduct 1x so you get 7x
You add up 12 and 1 which gives 13</span>
