I need help please! I'm stuck and I gotta get this test done, it's only 5 screenshots that has 5 questions, that's all. I would really truly appreciate it thank you! :)

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

Solve the inequality and graph 6j - 7 < 5

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.
