First, you would multiply 2.5 by 8, getting 20, to find the area. Then, multiply 20 by 12 to convert it into inches, getting 240 inches squared as the area. Then, multiply 2.5 by 6, getting 15, to find the area of each tile. Finally, divide 240 by 15, getting 16, to find the number of tiles needed.

Answer:
x = -1/2 , 4
Step-by-step explanation:
1) If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
2x+1=0
x−4=0
2) Set the first factor equal to 0.
2x+1=0
3) Subtract 1 from both sides of the equation.
2x=−1
4) Divide each term by 2 and simplify.
2x/2= −1/2
5) Cancel the common factor of 2.
x= −1/2
6) Move the negative in front of the fraction.
x = −1/2
7) Set the next factor equal to 0 and solve.
x=4
8) The final solution is all the values that make
(2x+1)(x−4) = 0 true.
9) x = −1/2 , 4
