Multiply r^2+7r+10/3 by 3r-30/r^2-5r-50 
<span>=( r^2+7r+10)/3 (3r-30)/(r^2-5r-50) </span>
<span>=(r+2)(r+5)/3 3(r+10)/ (r-10)(r+5) </span>
<span>=3 (r+2)(r+5)(r+10)/3(r-10)(r+5) </span>
<span>=(r+2)(r+10)/(r-10)</span>

Answer:

umm i think its r+2

Step-by-step explanation:

((r²+7r+10)/3) × (3r-30)/(r²-5r=50)= Factoring the expression (r²+7r+10) we get  (r+2)(r+5)

Then multiply it with the other numerator, we get = (r+2)(r+5)(3(r-10)

Then we factorise = (r²-5r-50) = (r+5)(r-10)

Multiplying it with the other denominator, we have; = 3(r+5)(r-10)

Therefore dividing (r+2)(r+5)(3(r-10)/(3(r+5)(r-10) we get; = r+2

Therefore, the correct answer is r+2 (NOT MY WORK) (YAY)

Which pair of statements describes the end behavior of the graphed function
Alex777 [14]

The statement (A) As x approaches negative infinity, f(x) approaches infinity. As x approaches infinity, f(x) approaches infinity is correct.

<h3>What is polynomial?</h3>

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n

We have a polynomial function:

\rm f(x) =  x^{3}+2x^{2}-5x-6

The function is a cubic function and the graph of the cubic function will be a curve.

As we can see in the graph, f(x) grows larger as x approaches negative infinity. f(x) also becomes closer to infinity as x does.

Thus, the statement (A) As x approaches negative infinity, f(x) approaches infinity. As x approaches infinity, f(x) approaches infinity is correct.

HELLO EVERYONE IT WOULD BE GREAT IF YOU CAN HELP ME IM ABOUT TO FAIL MY CLASS

Well we first need to add up all the purchases, 2 sandwiches are 6.86 each so by multiplying that we get 13.72. Next are the burgers, 3.44 x 4 is 13.76. We don’t need to multiply fries since there’s only one, so that’s just 3.19. Finally there are 4 drinks for 1.52 which gives us 6.08. We need to add these prices all together to get the total. 13.72 + 13.76 + 3.19 + 6.08 = 36.75. In order to find ten percent we multiply 36.75 by .10 which gives us 3.675. Double of 3.675 is 7.35. The price 13.72 (14 rounded) needs to be added with the tax 3.675 (4 rounded) and once again add 7.35. All together we get 25. Are there no other answer choices? Unless I did something wrong I’m sure this is right
