HOW DO I DO THIS PLEASE SOMEONE SOLVE IT AND I WILL MARK BRAINLIST!! PLEASE ITS DUE TODAY. LOOK AT THE IMAGE ABOVE

The 2 rectangles and triangles are similar to each other, so the corresponding sides between the same shape are proportional.

For the rectangle, 10 is 1 2/3 times greater than 6, so x is 12 times 1 2/3, which is 20. You can also think of it as 12 is 2 times 6 on the left rectangle, so x on the right rectangle is 2 times 10

For the triangle, the corresponding sides are NP and XZ, and XZ is 13 times as large as NP. The corresponding side to PO is ZY, and 7 times 13 is 91, so w is equal to 91.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
