Answer:

x = 13

Step-by-step explanation:

3x + 12 + 5x + 16 + 4x + 18 = 202

combine like terms

12x + 12 + 16 + 18 = 202

12x + 46 = 202

<u>        -46     -46 </u>

12x = 156

divide by 12

x = 13

Add all the sides together (don´t forget parenthesis) Put the x´s with the x´s and the same with the other numbers. The subtract additional numbers from the total. The divide what left from the number in front of the x.

(3x + 12) + (5x + 16) + (4x + 18) = 202

8x + 28 + (4x + 18) = 202

12x + 46 = 202

      - 46     -46

12x = 156

/12      /12

x = 13

I don’t understand how to find the dimension,<br> Need help :c
slava [35]

Width = W

Length = 2 times the width plus 3 feet = 2W + 3

Area of triangle A = L * W

A = W (2W + 3)

20 = 2W^2 + 3W

2W^2 + 3W - 20 = 0

(W + 4) (2W - 5) = 0

W + 4 = 0; W = - 4 (width cannot be negative, excluded)

2W - 5 = 0

2W = 5

W = 2.5

L = 2W + 3 = 2(2.5) + 3 = 8

Answer:

Width = 2.5 feet and Length = 8 feet

Hope it helps.
