O B. (4x + 7)(4x - 7)
O C. (8x-7)(2x-7)
O D. (4x-7)(4x-7)

Answers

Answer:

B

Step-by-step explanation:

16 x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b), thus

16x² - 49

= (4x)² - 7²

= (4x + 7)(4x - 7) → B

Answer:

B

Step-by-step explanation:

There is no number between 16x and 49. So only think about the number being squared for 49; which is 7.

Then 49 is negative, so you must have both positive and negative signs in both parenthesis. Otherwise, positive times positive is positive, and negative times negative is also positive.

4x4 is 16. That's why you put fours in front of Xs.

(1 pt) The conservation club has 32 members. There are 18 girls in the club. What is the ratio of girls to boys in simplest form?

Answers

how many boys are there? there are 32-18=14 boys! (check: 14+18=32; correct).

So the ratio of girls to boys is 18 to 14, or 18:14

both number are even, let's divide them by 2:

9:7

now they don't have any more factors in common so the answer is 9:7!

Answer:

9;7

A jewelry stand sells 5 different pairs of earrings. The earrings sell for $12, $9, $6, $8, and $10.What is the mean absolute deviation of the prices? Round to the nearest cent, if necessary.

$______

Answers

The answer is $1.6

Step 1. Find the mean of all values (X = ?).
Step 2. Find the distance of all values from the mean (d1, d2, d3, d4, d5).
Step 3. Find the mean of distances (D).

x1 = $12
x2 = $9
x3 = $6
X4 = $8
x5 = $10

Step 1.
X = (x1 + x2 + x3 + x4 + x5)/5
    = (12 + 9 + 6 + 8 + 10)/5
    = 45/5
    = $9

Step 2.
d1 = 12 - 9 = 3
d2 = 9 - 9 = 0
d3 = 9 - 6 = 3
d4 = 9 - 8 = 1
d5 = 10 - 9 = 1

Step 3.
D = (d1 + d2 + d3 + d4 + d5)/5
    = (3 + 0 + 3 + 1 + 1)/5
    = 8/5
    = $1.6

Find the difference. express your answer in simplest form. (4r/s) - (r/s)

Answers

For this case we have the following expression:
 (4r / s) - (r / s)
 We observe that we have the term r / s in the whole expression.
 Therefore, we can draw common factor.
 Rewriting we have:
 (r / s) * (4-1)
 (r / s) * (3)
 3 (r / s)
 Answer:
 
the difference is:
 
3 (r / s)
your answer would be 4 because r/s - r/s would be 0 so you have 4 left hope this helps you!!!!
