Answer:
x-intercepts: (2,0), (4,0)
y-intercepts: (0,-8)
Explanation:
To find the x intercept(s), you must compute where y=0. So solve 0= -x^2 + 6x - 8. So, the x intercepts are: (2,0) and (4,0) since the solutions to the mentioned equation are x=2 and x=4. To find the y intercept(s) compute what is y when x=0. In this case, when x=0, y=-8. So the only y intercept is (0,-8).
30 * 11.95 = 358.5 so mr kaplan will end up paying $358.5

area if a square: side length x side length (s^2)
7 x 7 = 49
Answer:
She will need 4 square and 8 triangular pieces.
Step-by-step explanation:
For every 6 pieces of cloth, 2 are squares.
So, for 12 pieces of cloth, the no. of square pieces would be,
= 
= 4
As the remaining pieces will be triangles, so the no. of triangular pieces will be, equal to,
(12 - 4) = 8
X^2 - 8x = (x - 4)^2 - 16
we add 16 to give x^2 - 8x + 16 which is a perfect square
x^2 - 8x + 16 = (x - 4)^2
answer is 16
