Factor out common factors.
-x³-4x²-5x = -x(x² + 4x + 5)
-x(x² + 4x + 5) is your answer
hope this helps
2+2 = 4 therefore four as a fraction would just be four wholes —-> 4/1
11. The sum of these two angles is equal to 180.
So, 3x-4/2+4x+x/2+2=180.
Combine like terms: 4x-4/2+4x+2=180
Find and replace common denominator: 4x-4/2+8x+4/2=180
Combine like terms: 12x/2=180
Simplify: 6x=180, x=30
Check: 90-4/2=43, 120+15+2=137, 43+137=180
Answer:
15(2r^2+2r+5)
Step-by-step explanation:
I'm more of a guess and check type of person, but 15 x 2r^2 = 30r^2, 15 x 2r = 30r, and 15 x 5 = 75
