Answer:
= 6
Step-by-step explanation:
in the third step, they did 2 x -12 and got 24. It should’ve been -24 since it was a positive times a negative. It shouldve been
-24 - (-30)
-24 + 30
= 6
Answer:
8 spoons and 9 forks
Step-by-step explanation:
2 F + 1.2S = 27.60
6 F + 5.5S = 98
solve system of equations
The solution would
be like this for this specific problem:
(cos^2x-1)/cosx+1
cos^2x-1= (cosx+1)(cosx-1)
cosx-1

Answer:
base is 5
Step-by-step explanation:
the reason is 5 is because the formula of the parallelogram is base times height
since they gave us the area which is 20 and we have the height we have to do the opposite of multiplying which is divide so we divide 20 with 4 which gave is 5 as our base and to check 4 times 5 is 20 so its correct
Let's call the midpoint of GF M.
MF = 16/2 = 8
KF = 25.89
MK = sqrt(25.89^2 - 8^2)
MK = 24.62
MKF = 8 * 24.62 / 2 = 98.48 square units for one triangle
There are 20 of those triangles that make up the decagon.
Therefore the total area = 20(98.48) = 1969.6 which would be option C
