Hello from MrBillDoesMath!
Answer:
(y+ 5/6)^2 = 169/36
Discussion:
3y^2+5y=12 => (divide both sides by 3)
y^2 + (5/3)y = 12/3 = 4 =>
Add\subtract the square of one-half the coefficient of y:
( y^2 + (5/3)y + (5/6)^2) - (5/6)^2 =4 (add (5/6)^2 to both sides)
(y^2 + (5/3)y + (5/6)^2 = 4 + (5/6)^2 =>
(y+ 5/6)^2 = 4 + (5/6)^2 = 4 + (25/36) =
(144+25)/36 = 169/36
So
(y+ 5/6)^2 = 169/36
We can also solve for y by taking the square root of both sides:
(y + 5/6) = sqrt(169/36)
= +\- 13/6 ( as 169 = 13*13 and 36 = 6*6)
y = (-5/6) +\- 13/6
Thank you,

Answer:
The surface area is equal to
Step-by-step explanation:
we know that
The surface area of the cylinder is equal to
where
B is the area of the base of cylinder
P is the circumference of the base of cylinder
h is the height of the cylinder
<u>Find the area of the base B</u>
we have
substitute
<u>Find the circumference of the base</u>
we have
substitute
<u>Find the surface area</u>
we have
substitute
The answer is less than because if you grab a calculator and do 8 squared then you get 2.82842712475.
Answer:
1 or 2 i think 2
Step-by-step explanation:
3/4 of a Mile
3/8+3/8=6/8
Both 6 and 8 can be divided by 2 so divide them by 2 to get 3/4
