Let x be the length of the garden
and y be the width of the garden.
since you only enclose 3 sides of the garden by a 40 ft fence. so the equation for this is:
2x + y = 40
and the area of the garden is 100 sq ft, so in equation
xy = 100
from equation 1, 2x + y = 40
y = 40 - 2x
substitute to equation 2
xy = 100
x ( 40 - 2x) = 100
40x - 2x^2 = 100
2x^2 - 40x + 100 = 0
x = 2.9 ft
y = 34.5 ft
Answer:
315 inches long
Step-by-step explanation:
180 x .75= 135 <--- that is 75% of 180
then add the two numbers
180 + 135
you add them because the original length of the car is 180 inches and the truck is 75% longer.
180 + 135= 315
Try to divide 62.01÷ 9 and then do it with the other one
Answer:
bro how she got 12 campers
Step-by-step explanation:
Answer:
2x² + 4x + 3
Step-by-step explanation:
Given:
f (x) = 2x +1
g(x) = x² + 2x + 1
to find f(g(x)), simply take the x-terms in f(x) = 2x+1 and replace them with g(x) = x² + 2x + 1
Hence,
f(g(x))
= f(x² + 2x + 1)
= 2(x² + 2x + 1) + 1
= 2x² + 4x + 2 +1
= 2x² + 4x + 3
