Answer:
(x+9)(x+2)
Step-by-step explanation:
x(x+9)+2(x+9)
(x+2)(x+9)
the order of the (---) doesn't matter
The answer is C-2x because you can substitute a number between -1 and 0 for x, so for example .5, and try out all the choices with .5. Ultimately you get 2(.5) as the largest number, so the answer is C.
Answer:
Step-by-step explanation:
Problem 2a
The total number of ways that he can deal with his room
is 3 * 2 * 3 = 18
Problem 2b
P(green, plaid, track) = 1/3*1/2*1/3 = 1/18
Problem 2C
The bedspread and the poster don't change. The word or in probability is a real stinker. In this case it means that there are 2 choices of paint color.
The only choice that won't work is if he chooses hospital white instead of green or blue. So he has a 2/3 chance of choosing one of the two colors he wants.
The probability then becomes P(bedspread,Poster, color) = 1/2 * 1/3 * 2/3 =
2/18
2.25t+5= 13.5t+14
-2.25t -2.25t
5= 11.25t+14
-14 -14
-9= 11.25t
-9/11.25=t
t= -0.8
