<span>In here, we will use the slope formula in order to prove that ABCD is a parallelogram. The slope of AB must be equal to CD and the slope of BC must be equal to DA. Using the formula m = (y1-y2) / (x1-x2), we obtain the slope for AB = 0/4, BC = 1, CD = 0/4, DA = 1. We can say that ABCD is a parallelogram as it satisfies AB = CD, and BC = DA</span>

Answer:

I would say not here D.

Step-by-step explanation:

Because I found the area of the base first *the square* which is 4 x 11 = 44 and the rectangles are 4 x 14= 56 x 2 since there are 2 rectangles is 112. Then the triangles are 11x14=154/2=77 x 2 since there are 2 triangles is 154. Then we add up all those numbers 44+112+154= 310 not 308 *C*.

Hope I was able to help!

32.5% of what number is 78.65

Alex777 [14]

To find this answer, all you have to do is reverse it. To start off, 32.5x = 78.65, from the problem. Then, all we do is solve for x by dividing both sides of the equation by 32.5, yielding x = 2.42.

I hope this helps, and mark brainliest if you want! :)
