Answer:
Step-by-step explanation:
r²+8r=−7
Step 1: Subtract -7 from both sides.
r²+8r−(−7)=−7−(−7)
r²+8r+7=0
Step 2: Use quadratic formula with a=1, b=8, c=7.
r=

I believe the answer is 2.222222222
Answer:
Yes, that is correct.
Step-by-step explanation:
a would always have to be greater than b since you're just multiplying each variable by itself.
30 because the original ratio would be 16 to 14 but that reduces to 8 to 7 and then you just double the 7 to get 14 and then you add 16 and 14 together to get the total number of horses and elephants.
