S=4P+4Q
S=4(P+Q)
S/4=P+Q
S/4-P=Q
Q=S/4-P
use cross products
(3r+6) *2 = 9*(2r-4)
6r+12 = 18r-36 distribute
12 = 12 r -36 subtract 6r from each side
48 = 12r add 36 to each side
4=r divide by 12
Answer:

Step-by-step explanation:
Answer: Option 'B' and 'C' are correct.
Step-by-step explanation:
Since we have given that
A rocket was fired into the air.
The rocket reached a maximum height of 59 feet at point (3.5,59) as shown in the figure.
And it took the rocket 3.5 seconds to reach its maximum height.
and the rocket landed after 6.9 seconds, So option 'D' is false which states The rocket landed after 34 seconds.
The equation that represents the rocket’s height over time has two solutions is completely false as it has only one solutions.
Hence, Option 'B' and 'C' are correct.
