The length of a rectangular garden is three feet less than twice its width. If the perimeter of the garden is 42 fett, what is its length?

13 feet

Step-by-step explanation:

If the length is 3 less than 2x the width, you can set up the equation 2(2w-3) + 2(w) = 72 and solve. That gives you w = 8. Lastly plug it in and that gives you 13.

y=mx+b

step-by-step explanation:

m slope

b y-intercept

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
