Answer: " [C]: " 2x² − 2xy − y² " .

__________________________

Step-by-step explanation:

__________________________

Given the expression:

_____________________________________

" 2x² − 6xy + 4xy − y² " ;

We can combine the "like terms" :

__________________________

- 6xy + 4xy = - 2xy ;

and rewrite the expression:

__________________________

" 2x² − 2xy − y² " ; which corresponds to:

__________________________

Answer choice: [C]: " 2x² − 2xy − y² " .

What is the next fraction in the sequence? Simplify your answer. 3/4, 5/8, 1/2, 3/8,

erma4kov [3.2K]

Answer: 2/8.

Step-by-step explanation:

When we have this type of problem, the usual way to solve them is trying with known types of sequences.

I will start with the arithmetic sequence, where the difference between any two consecutive terms is a constant. And if we call this difference as D, we will have the recursive relation:

Aₙ = Aₙ₋₁ + D

To check if this sequence is an arithmetic sequence, we can take the first two terms and see the difference:

(5/8 - 3/4) = (5/8 - 6/8) = -1/8.

Now let's do the same, but with the second and third terms:

(1/2 - 5/8) = (4/8 - 5/8) = -1/8

The difference is the same, -1/8.

Now we can use the recursive relationship above and the last given term of the sequence to find the next one:

A₅ = A₄ + (-1/8)

A₅ = 3/8 - 1/8 = 2/8

Then the next fraction in the sequence was 2/8.

What is the simplified form of the following expression? 6c^2 + 2.5d - d + 2c^2 - 3d

motikmotik

Answer:

The simplest form would be:

8c² - 1.5d

Explanation:

To simplify an expression, we need to gather the like terms.

Like terms are the ones having the same variable raised to the same power

In the given expression:

6c² + 2.5d - d + 2c² - 3d

We have terms having c² and terms having d.

Therefore, we would gather them as follows:

6c² + 2.5d - d + 2c² - 3d

(6+2)c² + (2.5-1-3)d

8c² - 1.5d ......................> This is the simplest form

Hope this helps :)
