Answer:
13s+6
Step-by-step explanation:
the length of the third side =
37s+42- (14s+16+10s+20) =
37s+42 - 24s -36 =
13s+6
Since there are as many of these triangles as the polygon has sides (eight for an octagon), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the octagon: area of octagon = 8 * base * height / 2 = perimeter * apothem / 2 .
i hope this helped you :)
So you know the school donated 9 pies, so you want to know how many pieces are in 9 pies. (remember 8 pieces per 1 pie)
9 x 8 = 72
Next you subtract the amount you got to total amount.(224)
So 224 - 72 is 152.
152 is how many pieces of pie were sold by students.
To configure this number back to amount of pie, you basically need to divide by 8(number of pieces in 1 pie).
152 divided by 8 is 19. So 19 pies were sold by students.
Hope this helped!
