Answer:
The area of one trapezoidal face of the figure is 2 square inches
Step-by-step explanation:
<u><em>The complete question is</em></u>
The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown. What is the area of one trapezoidal face of the figure?
we know that
The area of a trapezoid is given by the formula

where
b_1 and b-2 are the parallel sides
h is the height of the trapezoid (perpendicular distance between the parallel sides)
we have

substitute the given values in the formula


For 16/18 it would be 8/9
For 10/15 it would be 2/3
X= 22.5 get the x by itself by dividing by 2
the difference from 40000 to the future value in 2020, namely 5 years later is simply the yield or interest amount.

7(-6) - 3
-42 -3
-45
Your answer is -45
