Jordana was shown this diagram of an isosceles trapezoid and its reduction. She was asked to find the perimeter of the reduced trapezoid. Her work is shown below.

Side B

Perimeter
10+ 10+4+4 = 28

The question is unclear to me, 30x3=10 WHAT, 30x3=90 not 10

And also it seems you already know the answer Perimeter=28cm

C.

Step-by-step explanation:

Jordana made a mistake when she calculated the length of side B.

answer:   the answer is 625.

step-by-step explanation:   given in the question that

we are to find the value of

to do so, first we need to find the value of 'm' from the given information and then raise the power to 8.

let us do it in the following way.

therefore,

thus, the answer is 625.
