PLEASE HELP ME THANK YOU

Answer 1

10
`x^(2)` -20x -12.5 inches

Explanation:

Triangle Area Equation:

Area of triangle =
`(1)/(2) * base * height`

base = 10x + 5

height = 2x - 5

1/2 (10x + 5) (2x - 5)

= 1/2 (20
`x^(2)` - 50x + 10x - 25)

= 1/2 ( (20
`x^(2)` - 40x - 25)

= 10
`x^(2)` -20x -12.5 inches
