Answer: The estimate is greater than the actual mass.
1. Calculate the square root: 5x4+7x5
2. Multiply 5x4=20 7x5 20+35
3. 20+35=55
It is x6 because one day we will come right here sweet heart
Well 500 (let's say) are adult deer and 90 are the fawns. 10% of 500 is 50 so 50 were killed while 90 fawns were born. They are growing because 90-50=40. So they grew by 40 fawns. So. 500-50+90=540 or 500+40=540.
