Answer:
x^4 -x^3 -4x^2-3
Step-by-step explanation:
f(x)=x^4−x^2+9
g(x)=x^3+3x^2+12
(f−g)(x)= x^4−x^2+9 - (x^3+3x^2+12)
Distribute the minus sign
(f−g)(x)= x^4−x^2+9 - x^3-3x^2-12
I like to line them up vertically
x^4 −x^2+9
- x^3 -3x^2-12

x^4 -x^3 -4x^2-3
Answer:
100 centimeters
Step-by-step explanation:
Area of a square is side x side= s x s or s²
If s² = 1 square meter
s = √1 = 1 meter
Each side is 1 meter. To convert to centimeters multiply by 100 since there are 100 centimeters in 1 meter.
Each side is 100 centimeters
Answer: 
Step-by-step explanation:
For this exercise you must use the followinG Trigonometric Identity:

In this case, given the right triangle PQR, you can identify that:

Then, the next step is to substitute those values into
:

And the final step is to solve for "QR" in order to find its value.
So you get that this is:
