area = 2x² + 7x - 4
the area (A ) of a rectangle = length × width
A = (2x - 1 )(x + 4 ) ← expand using FOIL
= 2x² + 8x - x - 4 = 2x² + 7x - 4
Joshua made $400.
4 * $60 = $240
3 * $40 = $120
2 * $20 = $40
$240 + $120 + $40 = $400
X= 23 degrees
To find this you first add up 124 and 33 which equals 157. Then you would subtract 157 from 180 because all triangles equal 180.
