Surface area = area of 2 triangular sides + area of the roof + area of the base.
= 2 * 1/2 * 6 * 4 + 2 * 5*7 + 6 * 7
= 24 + 70 + 42
= 136 units^2
Answer:
- K'(4, -4)
- L'(8, -4)
- M'(8, 8)
- N'(4, 8)
Step-by-step explanation:
Dilation centered at the origin multiplies every coordinate value by the scale factor.
K(1, -1) ⇒ K' = 4(1, -1) = (4, -4)
L(2, -1) ⇒ L' = 4(2, -1) = (8, -4)
M(2, 2) ⇒ M' = 4(2, 2) = (8, 8)
N(1, 2) ⇒ N' = 4(1, 2) = (4, 8)
The answer is n=5. I worked it out
