Your answer would be 8n³ + 6n² - 4n - 20.
The horizontal method for simplifying binomials is to simply multiply the terms in the first bracket by the terms in the second bracket. Written out, this looks like:
(2n² × 4n) + (4n × 4n) + (4 × 4n) + (2n² × -5) + (4n × -5) + (4 × -5).
Then, we just need to do the operations in the brackets, which gives us:
8n³ + 16n² + 16n - 10n² - 20n - 20
And finally we collect the like terms to simplify, which means doing 16n² - 10n² = 6n², and 16n - 20n = -4n, so the final answer is 8n³ + 6n² - 4n - 20.
I hope this helps!
Answer:
Its 3
Step-by-step explanation:
Answer:
10%
Step-by-step explanation:
24 R + 16 Blu + 10 Y + 22 G + 8 Bla = 80 total
Then you cant set up a proportion:
In order for 80 to become 100, you must multiply it by 1.25. That means in order to get X, the probability of pulling a black marble, you can multiple 8 x 1.25
8 x 1.25 = 10
Answer:
x = -19
y = 55
Step-by-step explanation:
Given:
y = –3x – 2 (rearrange)
3x + y = -2 -----> eq1
5x + 2y = 15 -----> eq2
multiply eq1 by 2:
6x + 2y = -4 -------> eq 3
By elimination: subtract eq2 from eq 3
( 6x + 2y) - (5x+2y) = -4 - 15
x = -19 (Answer)
substitute x = -19 into eq1
3(-19) + y = -2
-57 + y = -2
y = -2 + 57 = 55 (Answer)
Is there any picture that we can work with??
