Answer:
x=12
Step-by-step explanation:
.......................
If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5
Think: x= -6 is the equation of a VERTICAL straight line passing thru that x-value. If you meant "y equals 3, then your "solution" is the point (-6,3).
Note: Please do not type "=" preceded or followed by "equals." In this problem "equals" is OK and "=" is an unnecesssary (duplication).
Answer:
32 inches
Step-by-step explanation:
Assuming 76 inches is perimeter, we'll say that w is width
Length = 5w + 2
Perimeter = w + w + (5w+2) + (5w+2) = 76 inches
12w + 4 = 76
Subtract 4 on both sides
12w = 72
Divide 12 on both sides
w = 6

If the width is 6, then 5w + 2 = 5(6) + 2 = 30 + 2 = 32
---
Width - 6 inches
Length - 32 inches
Perimeter - 76 inches
