Three brothers have ages that are consecutive even integers the product of the first & third boys ages is 20 more than twice the seconds boy age.find the age of each of the boys

Answers

Let's say X is the first brother's age
x+2 is second brother, and x+4 is the third brother
Since the product of the first and third boy x(x+4) is 20 more than twice (20+x(x+2), our equation is x(x+4)=20+2(x+2)
Simplify from there and see what you get.

A square can be changed into a rectangle by increasing the width by 3 units. Which expression represents the area of the rectangle in square units? (A) x^2+8x+15 (B) x2+15 (C) 2x +8 (D) 2x+15

Answers

Letting x be the side-length of the square, the new rectangle has length x and width x+3. Thus, the area is (x)(x+3)=x^2+3x. This is not an answer choice.
