Answer:

Step-by-step explanation:

21x + 4x = 300 Put brackets around the first two terms.

(21x + 4x) = 300 Pull the x outside the brackets. Use the distributive property. Combine the left

25x = 300 Divide by 25

25x/25=300/25 Do the division

If n is even, which represents the first consecutive even integer after n?

kow [346]

Answer: $n+2$

Step-by-step explanation:

1. By definition, an even number is that number that can be divided by two.

2. Therefore, keeping this definition on mind, if you have an even number $n$ , the next consecutive even integer after it can be obtained by adding 2.

3. Then, you can conclude the expression that represents the first consecutive even integer after $n$ is:

$n+2$
