Answer:
73
Step-by-step explanation:
An equation to model this scenario would be 2s=28, with "s" being the string.
To solve for L, you need to isolate/get the variable "L" by itself in the equation:
S = 2HW + 2HL + 2WL Subtract 2HW on both sides
S - 2HW = 2HW - 2HW + 2HL + 2WL
S - 2HW = 2HL + 2WL Take out the "L" in 2HL and 2WL
S - 2HW = L(2H + 2W) Now divide (2H + 2W) to get "L" by itself
I think you can stop here, but if you need or want to simplify:
which looks longer so I don't know if you need to do this
Yes, you can use a method other than graphing to solve a system of equations. One of the most common ways is to use matrices. When you solve the matrix, you solve for the point of intersection.
