Answer:
-3a^2= -3*(-6)^2
Step-by-step explanation:
-3a^2 = -3*a^2 = -3*(-6)^2
Answer:
Part A: 7.58974359 gallons (I don't know if you needed to round so I kept the full number).
Part B: 8.871794872 gallons
Step-by-step explanation:
Part A's Steps:
First Step: 350 - 54 = 296
Second Step: 296 ÷ 39 = 7.58974359 (Round if you need to)
Part B's Steps:
First Step: 296 + 50 = 346
Second Step: 346 ÷ 50 = 8.871794872
6y^2 + 6y + 2y + 2 = 6y^2 + 8y + 2
The way you do this is basically multiplying the values in the brackets with 6y, and then adding that to the same values multiplied by 2.
The area of the big circle is 415.48 and the smaller one is 59.69 so divide 59.69 by that number and multiply by 100 then do 100- that number(14.37) to get 85.63%
