Combine like terms

Lets write this out:-

z² + z + 4z³ + 4z²

z² will become 1z² because when ever there is a varaible, and before it there is NO coefficient the coefficient automatically becomes 1. Same is with z. z will be come 1z.

Lets write it out again:-

1z² + 1z + 4z³ + 4z²

Combine like terms:-

1z² + 1z + 4z³ + 4z²
(1 + 4)z² = 5z²
1z + 5z² + 4z³

So, when combining like terms in z² + z + 4z³ + 4z² the answer is
1z + 5z² + 4z³.

A packing crate can hold 205 avocados. There were 7000 avocados picked at a large grove. The owner has 36 packing crates. Does h

larisa [96]

First, you would have to divide 7000 by 205. This gives you 34 & a remainder. The owner can't pack parts of a crate so yes he does because he only has 34 full crates to ship. Leaving him with 2 extra crates left.

Match the function to the correct parabola

Lisa [10]

Answer:

The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) = $\frac{1}{5} x^{2}$

Step-by-step explanation:

The coefficient of the x² decides how wide or narrow a quadratic graph is. If the coefficient is a fraction of 1, the smaller the fraction the wider the graph gets. If the coefficient is a number bigger than 1, the bigger the number, the narrower the graph gets.
