Answer:
y= 3x^{3} + 10
Step-by-step explanation:
* 3(x) = 3x
* 3(2) = 6
* x^{2} + 3x = 3x^{3} because you add the x's
* 6+4 = 10
hope that helps if not i can try to go more in depth :)
Answer:
The angles are neither complementary nor supplementary.
Step-by-step explanation:
The angles are complementary.
To be complementary they need to add to 90
The angles are supplementary.
To be supplementary they need to add to 180
The angles are neither complementary nor supplementary.
What do they add to?
138+31 = 169
They are neither complementary nor supplementary
We presume you want to add the two vectors.
<5, -2> + <0, 0> = ((5+0), (-2+0)> = <5, -2>
Answer:
(a + 1)²(a + 7).
Step-by-step explanation:
The original expression:
Factor each denominator:
Factor out
Multiply each term by the opposite denominator and add:
![= \frac{ 1}{a+1 }[\frac{a^{3}(a+7)-3(a+1)}{(a+1)(a+7)}]](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B%201%7D%7Ba%2B1%20%7D%5B%5Cfrac%7Ba%5E%7B3%7D%28a%2B7%29-3%28a%2B1%29%7D%7B%28a%2B1%29%28a%2B7%29%7D%5D)
Remove brackets:
![= \frac{a^{3}(a+7)-3(a+1)}{(a+1)^{2}(a+7)}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Ba%5E%7B3%7D%28a%2B7%29-3%28a%2B1%29%7D%7B%28a%2B1%29%5E%7B2%7D%28a%2B7%29%7D)
The least common denominator is (a + 1)²(a + 7).
