<h3>Final answer: 6/5</h3>
<u />
<u>SOLUTION</u>
• -4 = 5(p -2)
-4 = (5)(p) + (5)(-2) • Distribute
-4 = 5p + (-10)
-4 = 5p - 10
• 5p - 10 = -4
• 5p - 10 + 10 = -4 + 10
5p = 6
•
p =
- simplify both sides of the equation
- flip the equation
- add 10 to both sides
- divide both sides by 5
- we would be getting the final answer of 6/5

Answer:
Width = 6.5 inches
Length = 10.5 inches
Step-by-step explanation:
Let
"l" be length of rectangle
and
"w" be width of rectangle
Since length of rectangle is 4 inches MORE THAN WIDTH, we can write:
l = 4 + w
The perimeter is sum of all sides, so
Perimeter = l + l + w + w = 2l + 2w
The perimeter is 34, so we can write:
2l + 2w = 34
Putting 1st equation in 2nd, we get equation in "w" and solve for this first:
Width is 6.5 in
Now, l = 4 + w, so
l = 4 + 6.5 = 10.5
Length is 10.5 in
