Step-by-step explanation:
area of trapezoid=(a+b)×h divided by 2
=(9+19)×4 divided by2
=28×4 divided by2
=112 divided by 2
=56m square
4x - 12
You can get this by switch the f(x) and the x and then solving for the new f(x)
Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
Answer:
Box A = 37.3333333333
Box B = 23.33333333333
Box C = 9.33333333333

2y+y=9
3y=9
y=3
x=2y=2.3=6
