Step-by-step explanation:
A quadratic graph will surely help you find the solutions
X2-x-2=0
x1=2 x2= -1
Substitute each of the x value in the original equation to get the y value
(2)^2-(2)-2= 0 (2,0)
(-1)^2-(-1)-2=-2 (-1,-2)
plot the coordinates on the graph,the graph should be a curve
There would be 3 even numbers on a six sided dice. So, 3 / 6 = .50, or 50%
Answer:
14. 12x + 2y
16. -2x - 4y
18. -8x + 10y
Step-by-step explanation:
<h3><u>
Don't stress it.</u></h3>
All you need to do is add the x's with the x's and add the y's with the y's.
The same applies with subtraction.
<u><em>Note: </em></u>
positive + positive = positive
negative - negative = negative

Answer:
2, 700 cubic ft.
Step-by-step explanation:
The formula for volume = Length x Width x Height ( L x W x H)
11 x 10 x 22 = 2420
7 x 4 x 10 = 280
2420 + 280 = 2, 700
Answer:
x=6 and y= 15 I think im correct don't take my word for it
