5:8 and 20:32 would be a proportion.
Easy way to find this:
Set up the proportion as a fraction.
Use the cross product property. Multiply the diagonals and if the products of the diagonals are the same, then they are proportional.

Opens downward, like a frowning face
Step-by-step explanation:
Answer:
-15c + 2
Step-by-step explanation:
you start by multiplying the coefficients of the parentheses to the numbers inside which gives you
- c - 32c + 5 + 18c - 3
then you simply just group together the like numbers. all "c" 's go together and everything without a "c" goes together
- 1c - 32c + 18c= -15c
5 - 3 = 2
the final answer simplified is
-15c + 2
Given:
Triangle:
height = 6ft
base = 4ft
Rectangle:
length = x
Width = 6 ft
Surface Area = 150ft²
Area of a Triangle = h*b / 2 = (6ft * 4ft) / 2 = 12ft²
Area of a rectangle = Surface Area - Area of a Triangle
A = 150 ft² - 12 ft² = 138 ft²
138 ft² = x * 6ft
138 ft² / 6 ft = x
23 ft = x.
