The surface area is about 62.43750, or approximately 62.4 square feet. 1.25 times 62.4, the total cost is $78 to clean the rug.
There are two ways to do this. The first of which is the algebraic method. Plug in y = 0 and solve for x.
y = 4x - 2
0 = 4x - 2 ... y is replaced with 0
4x-2 = 0
4x-2+2 = 0+2 ... we add 2 to both sides
4x = 2
4x/4 = 2/4 .... divide both sides by 4
x = 1/2
x = 0.5
The x intercept is x = 1/2 or x = 0.5
--------------------------
The other approach is to graph the equation y = 4x-2, and mark where the line crosses through the x axis. You should find it crosses through x = 1/2 or x = 0.5; the x intercept as an ordered pair would be (1/2, 0) or (0.5, 0)
side note: the equation y = 4x-2 goes through the points (0,-2) and (1,2). You find this by plugging in x = 0 and x = 1 respectively to find the corresponding y values.
they need to be 8 each sides
well if 4 squares are = to 3 and its a cube then all the sides must be even
so if 3x2=6 and you need the square to have 6 as its sides then you need to get 4x2 which = 8
I think it is 28 but, i'm not completely sure. Hopes it helps
