Answer:
Option B.
Step-by-step explanation:
(f-g)(x) = f(x)-g(x)
= (5x²-3) - (x²-4x-8)
=5x²-3 -x² +4x +8 ( - sign outside will multiply each sign inside)
=4x² +4x + 5
Answer:
144ft
Step-by-step explanation:
Length x Wifth x height
Given that a side length is that means its parallel side is also 16. So 16 + 16 is 32 and 72 - 32 is 40 and 40 divided by 2, for two sides of the rectangle youll get 20. With the length being 20 and width being 16, 20 times 16 will get you 320m^2 which is the area.
Answer:
6715.486347 or 6715.49
Step-by-step explanation:
6200(1+.04/12)^12x2
This is a problem for which you will have to use the Pythagorean theorem.
The Pythagorean theorem states that:
x^2 + y^2 = h^2
where x and y are the legs, and h is the hypotenuse.
Let h = 20 ft, and x = 16
16^2 + y^2 = 20^2
Now, solve for y.
256 + y^2 = 400.
256 - 256 + y^2 = 400 - 256
y^2 = 144
y = 12
The length of the other leg is 12 feet.
