Rectangle HYGT has a perimeter of 170 inches. If the length is 10x - 7
frozen [14]

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 =    \frac{80}{16}

             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>

If f(x) = 3x + 12, find the value of x so that f(x) = 36.
Fynjy0 [20]

Answer:

The answer is 8 .

Step-by-step explanation:

f(x)=36

36=3x+12

36-12 and 12 -12

36-12=24

24 divided by the 3 that left in the equation equals 8 .

36=3x+12

-12       -12

24=3x

divided 24 by 3 and get 8
