Answer: 46
Step-by-step explanation:
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:
60 cm²
Step-by-step explanation:

Answer:
3:5 Is the ratio because there are five pieces of cheese.
Step-by-step explanation:
