Answer: 36 cm
Step-by-step explanation:
Given : The square has a perimeter =160 cm.
Perimeter of square = 4 (side)
Therefore , the side of square = (Perimeter)÷ 4
= 160 ÷ 4 = 40 cm
The new length of side after dilation = (Scale factor) x (Length of original figure)
For scale factor = 0.9
The new length of each side of the dilated square = (0.9)x(40)=36 cm
Hence, the new length of each side of the dilated square= 36 cm
3. if you buy 2 you will be down 4 cups. but if you buy 3 you will go over so the answer is 3
Im gona assume you mean
f(x) = 3x + 2 + 8x + 4. Add like-terms
Y = 11x + 6
0= 11x + 6
-6 = 11x
X= -6/11
