David currently has a square garden. He wants to redesign his garden and make
it into a rectangle with a length that is 3 feet shorter than twice its width. He
decides that the perimeter should be 60 feet.

Determine the dimensions, in feet, of his new garden.

Width=11 feet

Length = 19 feet

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations :

Where:

L= length

W= width

Replacing the value of L in the perimeter equation:

2(2W-3) +2W =60

4W -6+2W=60

4W+2W=60+6

6W=66

W=66/6

W=11

Replacing the value of W in the length equation:

L= 2(11)-3

L=22-3

L=19

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

none.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
