B. 54 meters
first you want to set up your ratios and cross multiply to figure out the number to square l's ratio. which would be 10.8.
then use formula for perimeter
2(l)+2(w)=9
2(10.8)+2(18)=53.6-rounded =54<span />
→Answer:
y = -17
→Step-by-step explanation:
Well first off the f(x) in the equation f(x) = 3x + 7 can also be written as y,
y = 3x + 7
So if x is -8 we need to plug it in for x and solve, simple as that :)
y = 3(-8) + 7
y = -24 +7
y = -17

Answer:
40
Step-by-step explanation:
The shape has 6 sides a,b,c,d,e,f
The perimeter is the sum of the sides
P = a+b+c+d+e +f
4 of the sides add to 195 a+b+c+d = 195 Replace in the equation
P = 195 +e+f
We know that e and f are equal
P = 195+f+f
P = 195+2f
The perimeter is 275
275=195+2f
Subtract 195 from each side
275 -195 = 195+2f-195
80 = 2f
Divide by 2
80/2 = 2f/2
40 =f
The other 2 sides are 40 ft each
