Answer:
2 and 3
Step-by-step explanation:
2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
side ratio: 1/4------- area ratio: 1²/4² = 1/16 = 1:16 ratio
3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.
The ratio of the perimeters is the same as the scale factor.
scale 1:4
Hey there!
4(9/4 + 5/7c)
= 4(9/4 + 5/7(-7))
= 4(9/4) + 20/7(-7)
= 4(9/4) - 20
= 9 - 20
= -11
Therefore, your answer is: -11
