Which of the binomials below is a factor of this trinomial? x^2-7x-44
2 answers:
Answer:
C. (x -11)
Step-by-step explanation:
The given trinomial is
Let's factor it. To find factor, we need to find the factors of -44 such that when you add them, we have to get -7
-44 = -11*4
- 7 = -11 + 4
so the correct factors are -11 and 4
Now we can write the middle term - 7x = -11x + 4x
Now let's group the first two terms and second two terms and factor it.
= x(x - 11) + 4(x - 11)
Here (x-11) is common factor, so we can take outside and rewrite.
= (x - 11)(x + 4)
So the factors are (x - 11) and (x + 4)
Answer is C. (x -11)

Answer:
The number of 32 Gigabit keys that can be fitted on the hard drive is 375.
Step-by-step explanation:
The question is:
If my hard drive has a capacity of 1.5 Terabytes, how many 32 Gigabit keys can fit on that hard drive?
Solution:
1 Terabyte = 8000 Gigabits
Then 1.5 Terabytes in Gigabits is:
1.5 Terabytes = (8000 × 1.5) Gigabits
= 12000 Gigabits
One key is of 32 Gigabits.
Compute the number of 32 Gigabit keys that can be fitted on the hard drive as follows:
Thus, the number of 32 Gigabit keys that can be fitted on the hard drive is 375.
Answer:
27 balls
Step-by-step explanation:
If Dianna and Becky stopped 9 out of 10 shots made against them.
It means they allowed in 1 out of 10 shots made against them.
This is best solved using ratios
Proportion of Shots Stopped : Proportion of Shots allowed=9:1
If the other team scores 3 points, it means the number of shots allowed =3
Let x be the number of shots stopped
Number of Shots Stopped : Number of Shots allowed=x:3
Therefore:
9:1=x:3
Cross multiplying
x=9 X 3 =27
Dianna and Becky stopped 27 balls from going into the net,
