Here ya go i don't need these points just be a kind person:D

Which of the following is true for the relation f(x)=2x^2+1

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 4 ln x=2ln25 a) x=5 b) x=25 c) x=625
