Answer: 2x+4+3(2x-1) is not equivalent to 8x-2. it is equivalent to 8x+1
Step by step solution:
Step 1 :
Equation at the end of step 1 :
(2x + 4) + 3 • (2x - 1)
Step 2 :
Final result :
8x + 1
Answer:
x = 3
width = 15
Step-by-step explanation:
perimeter of a rectangle = 2 * width + 2 * length
54 = 2 * width + 2 * length = 2 * (4x) + 2*(5x) = 8x + 10x + 18x
54 = 18x
divide both sides by 18 to isolate x
x = 3
width = 5x = 5 * 3 = 15
Answer:
72
Step-by-step explanation:
There are 12 inches in a foot.
Therefore in 8 feet there are 96 inches
Therefore the square floor is 96 * 96.
Therefore the area of the square floor is 9216 inches squared.
Each tile is 8 inches by 8 inches meaning it has an area of 64 inches squared.
9216 / 64 = 144.
Therefore 144 tiles are needed to tile the floor
Since each tile is 50 cents, 144 * 0.5 = 72
Therefore it costs 72 dollars to tile the floor.
