PLEASE HELP! I WILL MARK AS BRAINLIEST!! I REALLY NEED SOMEONES HELP!

Andrej [43]

Since this is subtraction, everything must be turned negative in the second polynomial.

(6x^2 - 5x) - (2x^2 + 3x - 2)

6x^2 - 5x - 2x^2 - 3x - (-2)

6x^2 - 5x - 2x^2 - 3x + 2

Now, reorder the terms to make it easier.

6x^2 - 2x^2 - 5x - 3x + 2

Now, just combine like terms.

4x^2 - 5x - 3x + 2

4x^2 - 8x + 2

There’s the answer!

Chet started to slow his eating speed down later in the evening. He was

ozzi

Answer:

The unit rate is:

1/8 turkey/per hour.

Step-by-step explanation:

As Chet was eating 1/4 of a turkey every 2 hours.

This tells us that every two hours, Chet will eat 175 1/4 of a turkey.

Unit rate basically means 'how much of something per 1 unit of something else'.

A unit rate is a rate with a denominator of 1 unit.

This means, in 1 hour, Chet will eat half of what he eats every 2 hours.

so Chet will eat $\frac{\frac{1}{4}}{2}=\frac{1}{8}$ of a turkey in 1 hour.

i.e.

$\frac{\frac{1}{4}}{2}=\frac{1}{8}$

Therefore, the unit rate is:

1/8 turkey/per hour.
