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)
