Answer:
64
Step-by-step explanation:
A square has equal side measurements meaning that each side is 8. To find the area, multiply the length by the width which would be 8 * 8 = 64.
Answer:
Step-by-step explanation:
So here we have a 45-45-90 triangle.
This a special right triangle were the sides across from the 45 degree angles can be considered x, while the hypotenuse is two square roots of x.
Here since we have the sides across from the 45 degree angle we can conclude that 
So if we wanted the hypotenuse we would just plug in this value of x like so:




Therefore the hypotenuse is 18.

Answer:
h(7) = 29
h'(7) = 44
Step-by-step explanation:
If
, to find h(7) we can substitute the values of f(7) and g(7) and we get:

To find the derivative, we know that the derivative of a sum of functions equals the sum of the derivatives of those functions.
This would mean that
, we can substitute the values for f'(7) and g'(7)
