What is the algebraic expression for "the difference between eleven times a number and four"?
11 - 4x
11x - 4
11x - 4x

Hi :) This is just a simple problem where you have to clearly understand each meaning of the word. The difference would signify a minus sign. Eleven times a number would be 11x, where x is a number. Then, you subtract four from it. The answer is 11x - 4.

Separating your figure into two separate parts would solve this problem.let's start with the square first. each of the sides of the square is 4 yards long. to find the area of a square, use the formula  a =   (area = side).a =  a = 16 next, we'll find the area of the triangle. the formula for the area of a triangle is  a =  bh (area =  base x height). the height of your triangle is made up of two 4 yard segments. the total for the height would then be 8 yards (4+4).a = (6  · 8)a = (48)a = 24 ydlet's combine to find the total area of the entire figure.square = 16 triangle = 24 ydadding them together, the total area will give you an answer of 40 yd.
