3x^2+9x-54
= 3(x-3)(x-6)
That’s your answer 3(x-3)(x-6)

The answer is 3(x - 3)(x + 6)

Factor common term from 3x^2 + 9x - 54
In this case, 3 is the common term. Hence:
  3(x^2 + 3x - 18)

Simplify by factoring (x^2 + 3x - 18). Hence:
 (x - 3)(x + 6)

Therefore: 3(x - 3)(x + 6)

Answer:

3

Step-by-step explanation:

j(2) means that x equals 2...

the first inequality in the function says that x is greater than or equal to 2

the second inequality states that x is greater than 2(not equal to) and is less than or equal to 5

the third one states that x is greater than 5

x applies to the first inequality since we know that x can be equal to 2

Now, to the number before the if

there is a 3 before the if in the first inequality

This means that if x is greater than or equal to 2 the y or the function would equal 3

therefore, j(2) would equal 3

I hope this helps!!!

Vector A has a magnitude of 6.00 units and is directed at 60° to the positive x-axis. Vector B has a magnitude of 6.00 units and
notsponge [240]

Answer:

C has a magnitud of 10.4 units and is directed 270° from the positive x-axis

Step-by-step explanation:

As it shows on the attached picture, the xA and xB have equal magnitudes but opposite directions, therefore they cancel eachother out in the x-axis.

However, the yA and yB are equal in magnitud, but have the same direction. So, the create a total vector the is completely on the y-axis and it's magnitude is 2*(sin(60°)*6)=10.4 units.

In order for C to cancel this vector, it's magnitude also needs to be 10.4 units, but pointing the other way. Therefore, the angle needs to be 270° from the positive x-axis.

Brenna ran a total of 8 miles over the course of 4 track practices. How many track practices would it take for Brenna to run 16
solong [7]

Answer:

8 in total

Step-by-step explanation:

8 miles in 4 track practices, that's 2 miles every practice, you just multiply or add. She needs 4 more track practices because 8 x 2 is 16, which is how many miles she runs every practice. If you put 4 more practices it would be 16 miles and 8 practices in total. Sorry if this didn't make sense or confused you, I'm not the best at explaining but you're answer for the total amount of practices is 8.
