Answer:
= -27a^3+108a^2-144a+64
Step-by-step explanation:
Simplify:
=64-144a+108a^2-27a^3
=64+-144a+108a^2+-27a^3
Answer
= -27a^3+108a^2-144a+64
Two numbers that multiply to -240 and add to -1 are -16 and 15
-16 x 15 = -240
-16 + 15= -1
Hope this helps!
Well you can graph it by plotting 3 points then drawing a line through these 3 points. The graph will be a straight line . By plotting 3 points you can be more sure if you are right, because if you make a mistake then they might not make a straight line.
Put y = 0 in the equation and find the x coordinate:-
x + 5(0) = -20
x = -20
So we have one point to plot:- (-20,0)
Putting x = 0 we get 5y = -20 so y = -4
Second point:- (0, -4)
Putting x = 5 say we get 4 + 5y = -20 so y = -25/5 = -5
so our 3rd point is (5, -5)

The numbers are "x" and "y";
Therefore, we can suggest this system of equations:
x+y=24 ⇒x=24-y
x/y=5
solve this problem by substitution method.
(24-y)/y=5
24-y=5y
-y-5y=-24
-6y=-24
y=-24/-6=4
x=24-y
x=24-4
x=20
Answer: the numer are: 20 and 4
