<span> When you want the x </span>intercepts<span> (x,0):. Set y=0 then solve for x</span>
Part A:
Let the width of the rectangle be = x inches
As given, the length of a rectangle is 3 more inches than the width so let the length of the rectangle be = x+3 inches
Perimeter is given as = 54 inches
Perimeter = 
Equation becomes:
=54

Part B:
Solving the equation we get




Hence, the width of the rectangle is 12 inches
Length = x+3 = 12+3 = 15 inches
Hence, length of the rectangle is 15 inches.
Answer:
-9 33 3 -9 -14
Step-by-step explanation:
Do you need step by step if so tell me
I'll leave the picture to you; draw a rectangle and write 2x+4 along the length and 4x along the width. We don't really know the aspect ratio of the rectangle until we know x so any rectangle is fine.
The perimeter is the sum of all four side lengths,
p = (2x + 4) + 4x + (2x + 4) + 4x
Answer: p = 12x + 8
