Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4
Answer:
x = 5
Step-by-step explanation:
This equation can be rearranged in order to easily solve.
First, rearrange the equation by simply flipping it.
3x + 30 = 9x → 9x = 3x + 30
Then, you may solve for x.
9x = 3x + 30 subtract 3x from both sides of the equation
6x = 30 divide by 6 on both sides of the equation
x = 5
