From this equation, we need to find the value of m
We first isolate the variable m with its coefficient from the other values, so:
m2.8 - 4.9 = -7.11
m2.8 = -7.11 + 4.9
A negative and a positive will make a negative,so:
m2.8 = -2.21
Next we isolate the variable m completely from the other value so we divide both sides by 2.8, so
m2.8 / 2.8 = -2.21 /2.28
m = -0.78
Therefore the value of m is -0.78
Let the length be x, the width will be (95-x)
the total cost for the lengths will be:
36×x×2=$72x
Total for width will be:
2*6*(95-x)=1140-12x
total amount will be:
72x+1140-12x=4260
solving for x we get:
60x=4260-1140
60x=3120
x=52 ft
thus length=52ft
width=95-52=43 ft
Check the picture below
it cannot be a negative value, since it's a side's length, thus is the positive one.
shorter leg is "s", longer one is "s+4" and hypotenuse is "s+8"
