Answer:

4x² + 14x + 12

Step-by-step explanation:

There are several different methods you can use to multiply binomials, but I will walk through the FOIL method.

First - Multiply the first terms of each binomial

2x · 2x

Outer - Multiply the outside terms of each binomial (the first term of the first binomial and the second term of the second binomial)

2x · 4

Inner - Multiply the inside terms of each binomial (the second term of the first binomial and the first term of the second binomial)

3 · 2x

Last - Multiply the last term of each binomial

3 · 4

Then you will add each product together to get the expression 4x² + 8x + 6x + 12. This is not our answer as we have to combine like terms to simplify.

After simplifying, 4x² + 14x + 12 will be the answer.

Solve 3 a. i and ii<br> And 3 b. i and ii

Inessa05 [86]

For 3a, we see that it states that the submarine is 800 feet below sea level. Since it is below sea level, it is negative (as sea level is 0) and therefore -800, making ii correct.

For 3b, since the elevation is -150 feet, and negative means below sea level, the reef is 150 feet below sea level, making i correct.

Rework problem 17 from section 4.1 of your text about a multiple-choice test in which each question has 4 choices only one of wh

12345 [234]

Answer:

probability that exactly 4 out of 9 questions are correct is 0.111

Step-by-step explanation:

Given data:

Test consist of multiple choice question which as 4 choices

Total number of answer randomly = 9

Probability of having 4 answer correctly is calculated as

p = probability of having particular question is answered in correct way

= 1/4 = 0.25

q = probability of having particular question is answered incorrectly

= 3/4 = 0.75

Binomial expansion is beneficial in various situations at which numerical variables are present that are countable or whole numbers

probability that exactly 4 out of 9 questions are correct

$= ^9C_4 (0.25)^4 (0.75)^5$

$= 120\ times 0.00390 \times 0.2373$

= 0.111
