I’m gonna go with C sorry if I’m wrong
I’m trying to get points ignore this, sorry i didn’t know how to help :(!
The Area of a Trapezoid can be calculated as:
Area = 0.5 x Height x Sum of lengths of parallel sides
From the figure, we can see the height, which is the perpendicular distance between two parallel sides is 12.6 inches.
The lengths of parallel sides is 19 and 29.2 inches.
Using the values in the above formula, we get:
Area = 0.5 x 12.6 x (19 + 29.2) = 303.66 square inches
So, the correct answer is option C
Multiply numerator and denominator by the conjugate of the denominator
Denominator: -10 + 8i
Conjugate of the denominator: -10 - 8i
Operation:
[9 +7i] / [-10 + 8i] * [-10 -8i] / [-10 - 8i] = [-90 - 72i - 70i +56] / [100 + 64] =
[-34 -142i] / 164 = [-17 -71i] / 82
