2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.

Answer:
(0, 2), (2/5, 0)
Step-by-step explanation:
In this slope-intercept form, the y-intercept is the constant in the equation: 2. That is the point of intersection on the y-axis is (0, 2).
__
When y=0, the value of x is the x-intercept.
0 = -5x +2
5x = 2 . . . . . . add 5x
x = 2/5 . . . . . divide by 5
The point of intersection of the graph with the x-axis is (2/5, 0).
Answer:
=468 m^2
Step-by-step explanation:
Surface area of a prism is
SA = 2 (lw + wh + hl) where l is length, w is width and h is height
SA = 2 ( 12*6 + 6*9 + 9*12)
= 2 ( 72+54+108)
= 2(234)
=468 m^2
Line parallel to y=x+11 so slopes are equal then
y= x+b
Passing through the point C (-6;2) then C belongs to this line
yc=xc+b
b= 6+2
b= 8
So y intercept is equal to 8
