The base of a side of a ramp is 3 meters and the height os 0.6 meters what us the area

The answer would be

area = base x height divided by 2

3*0.6 = 1.8/2=0.9 square meters

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
