Answer:
x = 1
Step-by-step explanation:
Given
8x - 2(x - 7) = 20 ← distribute parenthesis on left side
8x - 2x + 14 = 20, that is
6x + 14 = 20 ( subtract 14 from both sides )
6x = 6 ( divide both sides by 6 )
x = 1
Answer:
275 units^2
Step-by-step explanation:
The formula for the area of trapezoid is:
Area=((b1+b2)/2)*h
In the given trapezoid, as it can be seen
b1=16
h=11
The lower base will be calculated using all the lengths in the lower base
b2=9+16+9
b=34
Putting the values in formula
Area=((16+34)/2)*11
Area=(50/2)*11
Area=25*11
=275 units^2
