The answer is 5 planes - we count one for every side.
Hope this helped! Rate brainliest if you want. :)

Answer: x = 25</h3>
=======================================================
Explanation:
Add up the parallel sides, and divide by 2
x = (15+35)/2
x = (50)/2
x = 25
The midsegment is the average of the two parallel sides.
The range of values is =5m^4/p that is your answer
Answer:
{-π/2, π/2}
Step-by-step explanation:
Rewrite this as:
7sin^2 x - 14sin x + 7 = 0. Reduce this result by dividing all terms by 7:
sin^2 x - 2sin x + 1
Temporarily replace "sin x" with y:
y^2 - 2y + 1 = 0
Solve this through factoring: (y - 1)^2 = 0, or y - 1 = ± 0, or y = ±1
Recalling that y = sin x, we write
sin x = ±1, whose solutions are sin x = 1 and sin x = -1
The solution of sin x = 1 is π/2 and that of sin x = -1 is -π/2
and so the solution set is {-π/2, π/2}
Answer:
Bike=125 Skateboard= 74
Step-by-step explanation:
x + (x-51)= 199
2x-51=199
2x=250
x=125
125+ (125-51)=199
125+74=199
