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.

Analyze Lorena's work to determine which statements are correct. Check all that apply. In Step 1, she correctly distributed ‚Äì3

12345 [234]

Answer:

The answer is "The correct step are 1, 2 and 4 ".

Step-by-step explanation:

In the question some data is missing so, its correct question can be defined as follows:

In the given equation:

$\to \bold{5k -3(2k- \frac{2}{3}) -9 =0}$

Lorena's steps should be evaluated

In Stage 1: It is right because it allocates – 3 to parentheses appropriately, , that's why she has 5k-6k+2-9=0

In Stage 2: It is right because in this term 5k and 2k are merged, that's why she got -k-7=0

In Stage 3: It is not right because the propagation property of fair treatment was not used.

In Stage 4: It is right because it multiplies the variable on one of the two sides by -1. So, k=-7 to get.
