Area = length x width
Area = (5x + 1)*(3x - 2)
Area = 5x*3x + 5x*-2 + 1*3x + 1*-2
Area = 15x^2 - 10x + 3x - 2
Area = 15x^2 - 7x - 2 :)

What is the value of x?
ziro4ka [17]

Answer:

x =12

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

30 + 4x+2 = 8+6x

Combine like terms

32 +4x = 8+6x

Subtract 4x from each side

32+4x-4x = 8+6x-4x

32 = 8+2x

subtract 8 from each side

32-8 = 8-8+2x

24 = 2x

Divide each side by 2

24/2 =2x/2

12 =x
