Ответ:
C (12+1/2) hours
Step-by-step explanation:
The picture represents the number of hours she spend watching tv for 2 weeks.
One day she watched for 0 hours.
One day she watched for 1/4 hours.
One day she watched for 1/2 hours.
Three days she watched for 3/4 hours.
Three days she watched for 1 hours.
Four days she watched for (1+1/4) hours.
One day she watched for (1+1/2) hours.
So for those two weeks (those 14 days) she watched
0+1/4+1/2+3(3/4)+3(1)+4(1+1/4)+1(1+1/2)
1/4+1/2+9/4+3+[4+1]+[1+1/2]
(1/2+1/2)+(3+4+1+1)+(1/4+9/4)
(1)+(9)+(10/4)
(1+9)+(5/2)
(10)+(5/2)
(20/2)+(5/2)
25/2
(12+1/2)
Ответ:
-5x^2 - 25x + 3 (Answer B)
Step-by-step explanation:
Carry out the indicated multiplication:
2x^2 - 12x - 7x^2 - 13x + 3
Now rearrange these terms in descending order by powers of x:
2x^2 - 7x^2 - 12x - 13x + 3
Combining like terms, we get:
-5x^2 - 25x + 3 (Answer B)
