Estimate how many times 6 times 10 to the 20th power is than 29 times 10 to the 16th power

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

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12
