<h3>
Answer: Choice A</h3>
This is because we're adding -6 to each term, i.e. subtracting 6 from each term, to get the next term
- -2+(-6) = -8
- -8+(-6) = -14
- -14+(-6) = -20
- -20+(-6) = -26
and so on. The gap between adjacent terms is the same width. We say that the common difference is d = -6.
Answer: 2
Step-by-step explanation:
Answer: 6928
----------------------------------------------------------
Explanation:
We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.
Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000
Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072
Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928
This difference D is exactly equal to the shaded area.
