Which of the following is a perfect square? A. 169 B. 154 C. 279 D. 115

6 0

169 is a perfect square because 13*13 equals 169. You can find that this is the correct answer by taking the square root of the other values and seeing that the result is not whole numbers.

I recommend learning all of the perfect squares up to 25 as they will be very useful in Algebra/Calculus. Below I have attached a reference chart that you can use to learn them. The highlighted numbers are the perfect squares.

We use a system of equations to solve this. Since tri city sells 4 times it becomes 4x and solly company is x. Then we do 4x-x=96. 3x=96. x=32. We are not finished yet. We still have to multiply x by 4. x=128. Tri City sold 128 dishwashers.
