We are tasked to determine the difference between the two expressions such as 9+3x and 4+2x². In order for us to solve this, we need to arrange the terms in descending order such as shown below:
(3x + 9) and 2x² + 4
Then, we need to perform subtraction in the same terms only such as 9 and 4:
3x +9 - (2x² + 4)
3x + 9 -2x² - 4
3x + 5 - 2x²
Then arrange in descending order such as:
2x² + 3x + 5
The answer is 2x²+3x+5.
Answer:
Step-by-step explanation:
cos 4x cos 3x+ sin 4x sin 3x=cos(4x-3x)=cos x
Answer:
1.9
Step-by-step explanation:
Use triginometry to find the side length. So cosθ=
. Rearrange the equation so it looks like 2cosθ=?. We are given θ (20 degrees) so 2cos(20degrees)=?.
The missing length could be 11230 because you multiply all the numbers in which case it has to be 11230.
91.5 centimeters!
Because there is 30.5 centimeters in one foot, and 3 feet in a yard, you need to multiply 30.5 by 3 for each foot, or 30.5*3=91.5!
