Answer:
-39 2/3
Step-by-step explanation:
t - 122= 2t - 3
subtract 't' from each side to get:
-122 = 3t - 3
add 3 to each side to get:
-119 = 3t
divide each side by 3 to get:
t = -39 2/3
Answer:

Step-by-step explanation:
The formula of a volume of a cone:

r - radius
H - height
We have
r = (7 : 2) in = 3.5 in
H = 4 in
Substitute:


This is what we know:4x^2 + 12x + c = (2x + k)^2
<span>
4x^2 + 12x + c = 4x^2 + 2kx + 2kx + k^2
c=9
