Answer:
10w² - 35w + 3w² + 8w - 4w² + 9w
= 10w² + 3w²- 4w² - 35w + 8w + 9w
= 9w²- 18w
= 9( w² - 2w )

Answer:
approximately 6.708 feet
Step-by-step explanation:
We use the Pythagorean theorem to solve the problem, using 3 feet and 6 feet as the legs of a right angle triangle. The diagonal of the screen is therefore the "hypotenuse" of this right angle triangle, and can be determined via the formula:
which is approximately 6.708 feet
4. 54 + 63 + 54=171
5. 3+3+75=81
6. 20+68=89
7. 120+180=300 x 1.48=$444
The simplified expression should be
ab(5+9-1)
