Answer:
x+5 (under assumption you meant to do -3x
Step-by-step explanation:
you can use long division.
Take the leading coefficient x^4 and divide it by x^3. This results in x which is going to be the first part of you quotient. Now take that x and multiply it by the divisor (x^3 - 3). This gives you x(x^3 - 3) = x^4 - 3x. Now subtract that x^4 - 3x from the original polynomial and repeat this until you can't divide anymore
![x^4+5x^3-3x-15 - (x^4-3x) = 5x^3-15\\x^3/5x^3=5\\5(x^3-3) = 5x^3-15\\5x^3-15-(5x^3-15) = 0\\\\x+5](https://tex.z-dn.net/?f=x%5E4%2B5x%5E3-3x-15%20-%20%28x%5E4-3x%29%20%3D%205x%5E3-15%5C%5Cx%5E3%2F5x%5E3%3D5%5C%5C5%28x%5E3-3%29%20%3D%205x%5E3-15%5C%5C5x%5E3-15-%285x%5E3-15%29%20%3D%200%5C%5C%5C%5Cx%2B5)
Answer:
Y=5x+8
Step-by-step explanation:
Distribute then move 3 to other side and you get the answer.
Answer:
the sunflower seeds are a better deal when comparing unit price. The real question is why are we comparing raisins to sunflower seeds?
Step-by-step explanation:
14 raisins costs $2.94
This is $0.21 per raisin.
12 sunflower seed bags costs $2.40
That's $0.20 per bag.
[(-7)(-7)(-7) + (-7)(-7)(-7)] - [(-7)(-7) + (7)(7)]
(-343 + -343) - (49 + 49)
-686 - 98 = -784
The answer is a) -784 :)
Answer:
17
Step-by-step explanation:
18.50 - 2.50 = 16
16 divided by 0.90 = 17.7777777778
