Step-by-step explanation:

(p2qr+pq2r+pqr2)((−p)(q)+qr+−pr)

(p2qr)((−p)(q))+(p2qr)(qr)+(p2qr)(−pr)+(pq2r)((−p)(q))+(pq2r)(qr)+(pq2r)(−pr)+(pqr2)((−p)(q))+(pqr2)(qr)+(pqr2)(−pr)

−p3q2r−p3qr2−p2q3r−p2q2r2−p2qr3+pq3r2+pq2r3

[tex]\large\underline{\sf{Solution-}}[/tex]

Given that:

Opening the brackets,

[tex]\sf\longmapsto p^2qr(-pq+qr-pr) + pq^2r(-pq+qr-pr) + pqr^2(-pq+qr-pr)[/tex]

Opening the next brackets,

So,

Answers

Answer:

D. 5x - 1

Step-by-step explanation:

To solve this, you need to add together f(x) and g(x)

6, 12, 18, 24, 30, 36, 42, 48, 54 (the bolded numbers go in the box)

Step-by-step explanation:

1. To find the multiples of 6 between 6 and 54, we have to multiply 6 by numbers from 1 to 9.

6 × 1 = 66 × 2 = 126 × 3 = 186 × 4 = 246 × 5 = 30 6 × 6 = 36 6 × 7 = 426 × 8 = 48 6 × 9 = 54

Therefore, the multiples of 6 between 6 and 54 are 6, 12, 18, 24, 30, 36, 42, 48, 54. (again, the bolded numbers go in the boxes)

<1 and <2 are complementary. Solve for the measure of <1.

<1 = 12x + 4
<2 = 9x + 2

A. 52
B. 4
C. 38
D. 8.3

Answers

Answer:

A) 52

Step-by-step explanation:

If < 1 and < 2 are complementary angles, then it means that the sum of their measures add up to 90°.

< 1 + < 2 = 90°

12x + 4 + 9x + 2 = 90°

21x + 6 = 90°

21x + 6 - 6 = 90° - 6

21x = 84°

21x/21 = 84°/21

x = 4

Substitute the value of x = 4 into < 1 and < 2:

m < 1: 12x + 4 = 12(4) + 4 = 52°

m < 2: 9x + 2 = 9(4) + 2 = 38°

Therefore, the correct answer is A) m < 1 = 52°.

Answer:

$3.66

Step-by-step explanation:

5.00-2.00 = 3.00

0.95-0.29 = 0.66

3.00 + 0.66 = $3.66 which is the answer

Ok,so:

We don’t need the $ sign now.

So.

1. 5.95 -2.29 which is 3.66!

5 - 2 is 3, and 0.95 - 0.29 is 0.66.

So now add :3 + 0.66 is 3.66

So $3.66!

It took 35 seconds for 5 songs to download to Rebecca’s computer. The next day, it took 42 seconds for 6 songs to download. Write an equation in point-slope form to represent the time y it took to download x songs.

NEEDS TO BE STEP BY STEP

Answers

The equation in point-slope form to represent the time y it took to download x songs is; (y - 35) = 7(x - 5)

Since it took 35 seconds for 5 songs to download

and it took 42 seconds for 6 songs to download

In essence, we can represent the information as;

(5, 35) and (6,42)

To find the slope of the equation; we have;

Slope, m = (42-35)/(6-5)

m = 7

In essence, the equation in point-slope form to represent the time y it took to download x songs is;

(y - 35) = 7(x - 5)

Step-by-step explanation:

Step 1: Subtract 4x from both sides.

[tex]7x - 4x = 4x + 27 - 4x[/tex] [tex]3x = 27[/tex]

Step 2: Divide both sides by 3.
