I Graphed It
Step-by-step explanation:
Answer:
<h3>
second term minus first term </h3>
Step-by-step explanation:
Difference is a result of subtracting (not dividing!)
To calculate difference between two terms we have to subtract the previous from the next:

U=-2b+30
u+b=21
<span>in slope intercept form this is </span>
<span>u=-b+21 </span>
<span>The same thing for wheels is </span>
<span>2b+u=30 </span>
<span>or </span>
<span>u=-2b+30</span>
perimeter = 2width + 2 length
102 = 2(x+9) + 2x
102 = 2x + 18 +2x
102 = 4x +18
84 = 4x
21 = x
Length = x = 21 inches
Width = x + 9 = 21 + 9 = 30 inches
