Answer:
<em>The wide of the rectangle = 42 inches</em>
<em>The length of the rectangle = 43 inches</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the length of the rectangle = 10x-7
Given that the width of the rectangle = 6x +12
The perimeter of the rectangle = 2(length + width)
Given that the perimeter of the rectangle = 170
<u><em>Step(ii):-</em></u>
2(length + width) = 170
length + width = 85
10x-7 +6x +12 =85
16x +5 = 85
16x = 85-5 = 80
x =
x = 5
<u><em>Final answer:-</em></u>
<em>The length of the rectangle = 10(5)-7 = 50-7 = 43 </em>
<em>The wide of the rectangle = 6x +12 = 6(5) + 12 = 30+12 =42</em>
A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
The answer is d have a nice day
