Step-by-step explanation:
12r + t - 4r + 6t
=12r - 4r + t + 6t
=8r + 7t
(12r+2t) - (4r+10t)
=12r + 2t - 4r - 10t
=8r - 8t
=8(r-t)
12(r+t)-6(r+t)+4(r+t)-2(r+t)
=(12-6+4-2)(r+t)
=8(r+t)
Answer:
P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10
= 2(16) - 5(-8) + (-2) - 10
= 32+40-2-10
= 60
P(1) = 2(1^4) - 4(1^3) + (1) - 10
= 2 - 4 + 1 - 10
= -11
P(2). = 2(2^4) - 5(2^3) + (2) - 10
= 2(16) - 5(8) + 2 - 20
= 32-40+2-10
= -20
Answer:
The first from top shows correct representation on number line for -0.8 +0.6.
Step-by-step explanation:
When we add these two term we get
-0.8 is to left of origin so when we add any value it will shift to right .
For example
Such a way it ends to -0.2
We can do this two ways: polynomial division or synthetic division.
Polynomial division involves factoring the equations first. Synthetic division is basically long division.
I'm opting for polynomial division cause it's shorter.
First, we factor ((x^4)-(x^3)-(7x^2)+4x-3).
((x^4)-(x^3)-(7x^2)+4x-3)=(x-3)((x^3)+(2x^2)-x+1)
Then divide:
((x-3)((x^3)+(2x^2)-x+1)) ÷ (x-3) = (x^3)+(2x^2)-x+1
So your answer is B
