If they all painted at the same rate the equation is this
mothers 8
daughters 12 at 220 sq ft
mothers 6
daughters 8 at 152 sq ft
220 +152 =372 divided by 34 (because they all painted at the same rate)=10.94 sq ft they each painted

Answer:
141.4
Step-by-step explanation:
Plug the numbers into the formula, V=πr2h, you know that your radius is 3 and your height is 5, so you get V=π(3)2(5), you just then put it in the calculator. You get 141.37, round to the nearest tenth 141.4
The volume of the area is Length x width x height:
25 x 35 x 2/12 = 145.83 cubic feet.
1 cubic foot = 0.037 cubic yards:
145.83 x 0.037 = 5.40 cubic yards.
5.4 cubic yards x 1050 lbs/ cubic yard = 5,665.6 pounds.
Note:
Rounding and conversion may change the answer slightly, but I believe I rounded everything as it should be.
All ya got to do is break is down
Step 1) 4y(2y2+3y-5)-3(2y2+3y-5)
Step 2) 8y3+12y2-20y-3(2y2+3y-5)
Step 3) 8y3+12y2-20y-(6y2+9y-15)
Step 4) 8y3+12y2-20y-6y2-9y+15
Step 5) 8y3+(12y2-6y2)+(-20y-9y)+15
Then you got to simplify and you have to
Leave the
8y3 +
12-6= number y2 -
-20-9=- number y
Then leave the 15
Sorry your doing the same math as me so I get carried away :p
