Am i stupid because i'm advanced math and don't know what to do

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

Look at triangle wxy what is the length (in centimeters) of the side wy of the triangle?

What is the value of x in this triangle? a. 53° b. 62° c. 65° d. 118°
