The area of a square and a rectangle is given by multiplying the lengths of the sides of the square
A. The correct statements are;
The area of one square tiles <u>9·x²</u>
The area of the floor is <u>36·x⁶</u>
B. The number of tiles needed to cover the floor <u>324 tiles</u>
<u />
The reason the above values are correct are as follows:
A. The given parameters are;
The expression that represents the side lengths of the square room = 6·x³ feet
The side lengths of the square tiles = 3·x
Required:
To select the correct expressions
Solution:
The area of one square tiles = 3·x × 3·x = 9·x²
The area of the floor = 6·x³ × 6·x³ = 36·x⁽³ ⁺ ³⁾ = 36·x⁶
B. If x = 3, we have;
The area of the floor, = 36×3⁶ = 26,244
The area of one tile = 9 × 3² = 81
The number of tiles needed to cover the floor = <u>324 tiles</u>

Answer: OPTION C.
Step-by-step explanation:
Given a System of equations, you can use the Elimination Method to solve it by transforming the system in order to cancel out one of the variables. But first, the terms of both equations must be written in the same order.
To cancel out one of the variables, the coefficients must be opposites, which means that one must be positive and the other one must be negative.
Given the following System of equations:
You can notice that the order of the terms is not the same, so, if you want to use the Elimination Method to solve the system of equations, the first step you must apply is to rewrite the equations so like variable terms are in the same order.
Then:
