Answer:
102
Step-by-step explanation:
lets say x=2
so,
2x+2 would be 4+2
x would be 2
and 3x+8 would be 6+8
add up the sums,
6+2+80+14
and you get 102
so your answer is 102

If we rewrite this equation, it would look like this:

, which is the equation for a straight line with a slope of -4/3 and a y-intercept of 20. The y-intercept exists when x = 0. "x" represents the number of minutes he drives, "y" represents the number of laps he drives. Slope is rise/run, or y/x, which gives us that he drives 4 laps in 3 minutes (the slope of our line). The y-intercept, when x = 0, tells us that when he has driven 0 minutes, or hasn't driven at all yet, he still has 20 laps to go. When y = 0, the x-intercept is

, and

. Multiply both sides by 3 to get that -60 = -4x and that means that x is 15. This means that from start to finish, it takes him 15 minutes to drive the 20 laps.

If there was a number other than 0 before the decimal point, it would serve as the whole number in our final answer.
First count the number of digits after the decimal point. For this problem it's 4.
Then make the denominator 10 raised to the power of your answer in the first step so the denominator for this question is 10⁴=10000
The numerator will be the number after the decimal point.
The fraction will be = 112/10000
Then reduce it to the lowest term
If you divide the numerator and denominator by 16 you get
7/625 which is the lowest possible fractional term.
(Volume for a rectangular shape is length x width x height)
We can split up this 3D composite figure into two main parts (as shown in the picture I attached), and find each part’s volume before adding them together for the total volume.
Cube —> 5x5x5 —> 25x5 = 125 in^3
Rectangular Prism —> 20x5x5 —> 100x5 = 500 in^3
125 + 500 = 625
So the answer is A. 625 in^3
Hope this helped! If I was correct, I’d appreciate it if you marked my answer as Brainliest.
16b. Always. (Not sure why ‘Sometimes’ was wrong. It will be coplanar if they are in the same plane.
16c. Never. If two planes intersect, they intersect through half of the plane, not a point of the plane.
