First graph your x and y intercept then pick any two points on the line.

that's the equation used to find your slope
Example:
(4,2) (8,6) let's say those are the points you pick from the line
so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)
then subtracts 8-4=4 (8is your x2 and 4 is your x1)
then your left with

if you can reduce the reduce in this case you can which leaves you with

and that's how you find the slope
Angles in a triangle total 180°
180=128+5x+10+9x
180-128-10=5x+9x
42=14x
x=3
Answer:
76 square feet
Step-by-step explanation:
surface area = 2(wl + hl + hw) w=width h=height l=length
surface area = 2(5*4 + 2*4 + 2*5)
surface area = 2(20 + 8 + 10)
surface area = 2(38)
surface area = 76 square feet
Answer:
-101,430
Step-by-step explanation:
23 x 98 x 45 x 1 equals 101,430, but the real trick of the question is whether it is positive or negative.
23(-98) forms a negative number (-2,254)
-2254(-45) forms a positive number (101,430)
101,430(-1) forms a negative number (-101,430)
