What is the unknown symbol:
4 × {[(8 + 5) × 4] - [(18 __ 9) × 3]} = 100

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

What is the best way to answer questions with a x expression in the question. for example 3x + 10x=?
