B. adding 40 to both sides of the equation
x^2 - 40 = 0
x^2 = 40
x = ± √40
Answer:
The answer is 3.6 acres per day
Step-by-step explanation:
To find the unit rate divide the number of acres by number of days
∴ Unit rate =
÷ 
= (6 × 4 + 3)/4 ÷ (1 × 8 + 7)/8 = 27/4 ÷ 15/8
= 27/4 × 8/15 = 18/5 = 3.6 acres per day
John Is Correct. We Know That 18 / 3 = 6, Then We Need To Multiply By 2 minutes. It Will Take Exactly 12 minutes.
Answer:
-3x + 6

so you have 14+(-5) which is just 14-5
it gives you 9
