Simplify
(8x + 3)(2^2+ 8x +9)

Answers

Answer 1

Answer:

64x²+128x+39

Step-by-step explanation:

(8

Answer 2

Answer:

First distribute (8x + 3) into (2^2+ 8x +9)

16x^3 + 64x^2 + 72x + 6x^2 + 24x +27

Then we'll order the pairs from highest to lowest degree

16x^3 + 64x^2 + 6x^2 + 72x + 24x + 27

Then we'll add up the like terms

16x^3 + 70x^2 + 96x + 27

That should be your final answer simplified.

What are Exponents and Powers?

Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.

For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.

Given:

[tex]n^5[/tex] x n²

Using the Property of Exponents and power

[tex]a^m[/tex] x [tex]a^n = a^{m+n[/tex]

So, [tex]n^5[/tex] x n²

= [tex]n^{5+2}[/tex]

= [tex]n^7[/tex]

= n x n x n x n x n x n x n

Hence, the exponents is n x n x n x n x n x n x n.

Step-by-step explanation:

1.

Zero's

x = -3i, x = 2 and the third zero is x = 3i

Polynomial is:

(x + 3i)(x - 3i)(x - 2) =(x² - 9i²)(x - 2) =(x² + 9)(x - 2) =x³ - 2x² + 9x - 18

x = 3, x = 3, x = -1

Polynomial is:

(x - 3)(x - 3)(x + 1) = (x² - 6x + 9)(x + 1) =x³ + x² - 6x² - 6x + 9x + 9 =x³ - 5x² + 3x + 9

Scientific Calculator

Answers

Answer:

-39

Step-by-step explanation:

This sequence follows the pattern of subtracting 7 each time. We can prove this:

31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10

So if we were to continue to the 11th term, we would subtract 7 more times.

1. 10 - 7 = 3

2. 3 - 7 = -4

3. -4 - 7 = -11

4. -11 - 7 = -18

5. -18 - 7 = -25

6. -25 - 7 = -32

7. -32 - 7 = -39

The 11th term in the sequence would be -39.

The table shows the types of movies and the number of DVDs reented by customers at a Red Box in one

Based on the data in the table, what is the probability that a random customer will not rent a drama?

Answers

Answer:

A

Step-by-step explanation:

The probability that a random customer will not rent a drama is 4/5. Option B is correct.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

here,
Total number of rented DVDs = 25 + 36 + 52 + 12 = 125
Number of Drama movies = 25

The probability that a random customer will rent a drama.
P(D) = 25 / 125 = 1/5

Now,
The probability that a random customer will not rent a drama,
P(D)' = 1 - P(D)
       = 1 - 1/5 = 4/5

Thus, the probability that a random customer will not rent a drama is 4/5. Option B is correct.
