Answer:
Step-by-step explanation:
(3x + 1)/x = 1/(x -3) Cross multiply
(3x + 1)(x - 3) = x Remove the brackets. Use FOIL
f:3x*x = 3x^2
o:3x*(-3) = -9x
i:1*x = x
L : 1 * - 3 = -3
FOIL: 3x^2 -9x +x - 3
FOIL: 3x^2 - 8x - 3
3x^2 - 8x - 3 = x Subtract x from both sides
3x^2 - 8x -x - 3 = 0 Combine
3x^2 - 9x - 3 = 0 Factor
It's rather ugly. I had to use the quadratic equation
a = 3
b = - 9
c = - 3
x1 = 3.3
x2 = - 0.3
There is 110 slices of bread total in 5 loaves.
170/8=22
22*5=110
Answer: The surface area of the sides of the sandbox that Gabe wants to paint is 47ft2
Step-by-step explanation:
Hi to answer this we have to apply the formula:
Surface Area of a rectangular prism = 2lw + 2wh + 2lh
Where:
l= length
w= width
h= height
Since the sandbox is open , it has one less surface (length x width), we have to add only one lw term.
Surface Area of the sandbox = lw + 2wh + 2lh
A = (4x5) + 2( 5x1.5) + 2( 4x1.5)
A = 20+15+12
A= 47 ft2
3/16 is the answer the answer
