Answer:

89406, 89408 and 89410.

Step-by-step explanation:

Let n be the any even integer.

So n+2 will be 2nd even integer and n+4 will be 3rd even integer.

We are told that twice the first integer added to the third is 268,222.

Twice the first integer will be 2*n.

We can represent this information in an equation as:

2n+(n+4)=268222

2n+n+4=268222

3n+4=268222

Let us subtract 4 from both sides of our equation.

3n+4-4=268222-4

3n=268218

Let us divide both sides of our equation by 3.

\frac{3n}{3}=\frac{268218}{3}

n=89406

Therefore, our 1st even integer will be 89406.

2nd even integer = n+2

n+2=89406+2=89408

3rd even integer = n+4

n+4=89406+4=89410

Therefore, our three consecutive even integers will be 89406, 89408 and 89410.

Which of the following expressions is equal to 2x2 + 18 ?
ehidna [41]
<h3>Answer: Choice C. (2x - 6i)(x + 3i)</h3>

Work Shown:

2x^2 + 18

2(x^2 + 9)

2(x - 3i)(x + 3i) .... see note below

(2x - 6i)(x + 3i)

Note: I used the rule that a^2 + b^2 = (a - bi)(a + bi). I recommend FOILing out the right hand side to confirm the equation is true. You'll use the idea that i^2 = -1.
