Answer:
15 cm
Step-by-step explanation:
Write out the formula: a^2 + b^2 = c^2
Plug in the numbers that you were given: a^2 + 6^2 = 16^2
Solve for the numbers that you were given: a^2 + 36 = 256
Subtract: - 36 = - 36
a^2 = 220
Then, you find your answer: a^2 = 220
The square root of 220 is 14.832396974191326. But you are going to round it and you get 15. So, the answer is 15 cm.

Answer:
970m^{2}
Step-by-step explanation:
This polygon can be divided in two figures: one is a triangle, an the other one is a square.
We'll begin calculating the triangle's area, using the following formula:

Where:


As you can see, I added both sides of the triangle that measure 9 m and also the lenght of the square that measures 20 m! This added up is what the base of the triangle measures on total.



Now we are going to calculate the square's area, that is much more simple:

Where:


To know the whole figure's area, we add up both areas:

since she paid $5 admission subtract it from $7.25
that is $2.25
then 2.25/ 0.75 and its 3

Answer:
Step-by-step explanation:
f(x) = x²-2
g(x) = 4x-2
f.g(x)= x²-2(4x-2) = x²(4x-2)-2(4x-2) = 4x³-2x²-8x+4
f.g(x) = 4x³-2x²-8x+4
