Answer:

$-2r+4$

Step-by-step explanation:

$-8(r-2)+6(r-2)$

Distribute:

$(-8)(r)+(-8)(-2)+(6)(r)+(6)(-2)\\-8r+16+6r+-12$

Combine like terms:

$(-8r+6r)+(16+-12)\\-2r+4$

-2r + 4 is your answer.

What is the distance between points v (3,3) and w (-2,-3) round to the nearest tenth if necessary

Vinil7 [7]

Answer:

7.81 u

Step-by-step explanation:

<u>Given :- </u>

Two points (3,3) and (-2,-3) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

$:\implies$ D = √{(x2-x1)² + (y2-y1)²}

$:\implies$ D =√[ (3+2)² +(-3-3)²]

$:\implies$ D =√[ 5² +6²]

$:\implies$ D =√[ 25 +36]

$:\implies$ D = 61

$:\implies$ D = 7.81

<h3>Hence the distance between the two points is 7.81 units .</h3>

What is the difference of the polynomials?

Vilka [71]

Answer:

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

Step-by-step explanation:

We want to simplify;

$(8r^6s^3-9r^5s^4+3r^4s^5)-(2r^4s^5-5r^3s^6-4r^5s^4)$

We expand the bracket to obtain;

$8r^6s^3-9r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6+4r^5s^4$

We now group the like terms to obtain;

$8r^6s^3-9r^5s^4+4r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6$

We now simplify to get;

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

The correct answer is C

Margo is practicing her free throws for basketball

kipiarov [429]

Answer:

Step-by-step explanation:

Well if you think about it, if she has a total of 10 attempts she has to make 8 of them to make it on the team. Now the total attempts is double so we double the number of throws she needs to make in order to make the team so to do this we would do 8*2 which is 16. She needs to make 16 throws to make it on the team.
