I. Imagine you are a carpenter. You want to make a bench with three sides that faces an outdoor fireplace. The sides of the bench will all be equal lengths, and
they will be joined at 45-degree angles. The open side of the trapezoid that’s
formed—the part that faces the fireplace—has to be 90 inches wide. How long
should each side of the bench be?

rounding to the nearest thousandth would be 452,000

3x + 4y -25 =0 represents the amount of change sianna should recieve

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

10 b/c 5*2 =10
