Answer:
28.8
Step-by-step explanation:
Question #1:
Just divide the side lengths to find the scale factor.
8 / 2 = 4.
Therefore the scale factor from MNO to M'N'O' is 4.
Question #2:
Rotation rule for 180 degree clockwise turn: (-x, -y)
Therefore your new points will be:
(5, 2), (5, 4), and (4, 4)
1. Solve for x in 2x + 5 = 12
2x + 5 = 12 Subtract 5 from both sides.
2x = 7 Divide 2 from both sides.
x = 3.5
2. Substitute 3.5 in for x in 6x + 20
6(3.5) + 20
21 + 20
41
Your answer is 41.
“a” would equal 7!! hope this helps :)
