I think its the second one but just a fyi the site your on is ready and it looks like your doing the major test, not every answer on it are you suppose to get right its a test to see what you know and what you need to know
What they mean is plug in 3 for c, so it would be:
2 x 3(3+2) + 4(3+3)
the solution to the system of equation from the replacement set is -5
Given the equation −6z+1=−4−7z, we are to find the value of z from the given equation:
Given
−6z+1=−4−7z
Collect the like terms;
-6z + 7z = -4 - 1
Simplify the result
z = -4 -1
z= -5
Hence the solution to the system of the equation from the replacement set is -5

48 seconds, Consider what happens between one time that Ben and
Sally meet and the next. During this period Ben runs 30 (seconds)/80 (seconds/lap) = 3/8 of a lap. So Sally runs 5/8 lap in the same
time. Her speed is therefore 5/8 (laps)/ 30(seconds) which amounts
to 1 (lap)/ 48 (seconds).
