Challenge question: I will only mark brainliest and let you get all those pointsif you got everything correct and if you actuall

y need it. Otherwise I will report
Factor the following equations:

x^2 + 4x +3

x^2 + 5x + 6

Multiply the following:

(x-2)(x+3)

(2x-3)(x-4)

May the odds be ever in your favor! (By the way if you know where this quote is from without looking it up, I will probably mark you brainliest)

Have fun!

Factoring:


x² + 4x + 3

To solve, first find two numbers that multiply to 3 and add to 4. These two numbers would be 3 and 1. Write out the four terms and group them into two sets of two. Find the GCF (greatest common factor) of each set and factor it out futher.

x² + 4x + 3

x² + 3x + x + 3

(x² + 3x) (+ x + 3)

x (x + 3) + 1 (x + 3)

(x + 1) (x + 3)


x² + 5x + 6

To solve, first find two numbers that multiply to 6 and add to 5. These two numbers would be 2 and 3. Write out the four terms and group them into two sets of two. Find the GCF (greatest common factor) of each set and factor it out futher.

x² + 5x + 6

x² + 2x + 3x + 6

(x² + 2x) (+ 3x + 6)

x (x + 2) + 3 (x + 2)

(x + 3) (x + 2)


Multiply the following:


To solve these, you can use the FOIL method. When you FOIL, you multiply the First, Outside, Inside, and Last terms together; then, you combine like terms.


(x-2)(x+3)

x² + 3x -2x -6

x² + x - 6


(2x-3)(x-4)

2x² - 8x - 3x + 12

2x² - 11x + 12


That quote is from the Hunger Games! It's one of my favorite book series, and I'm sure I know almost all of the words to the movies by now. :)

Justify each step in solving the equation 6x = 3 (x + 4) by writing a reason for each statement.
BaLLatris [955]
First thing is to multiply 3 by x and get 3x,then 3 by 4 equals 12. 3x+12....6x=3x+12...subtract 3x from 6x and get 3x=12..then divide 3 on both sides and 3x crosses out.. and x=4...this is what I have to say about this..

Which statement best describes how to determine whether f(x) = 9- 4x4 is an odd function?
vitfil [10]

Answer:

Option C.

Step-by-step explanation:

Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.

Consider the given function is

f(x)=9-4x^2

If f(-x)=f(x), then f(x) is an even function.

If f(-x)=-f(x), then f(x) is an odd function.

Now, substitute x=-x in the given function.

f(-x)=9-4(-x)^2

f(-x)=9-4(x)^2

f(-x)=f(x)

So, the given function not an odd function. It means it is an even function.

To check whether the given function is odd, we have to determine whether 9-4(-x)^2 is equivalent to -(9-4(x)^2).

Therefore, the correct option is C.

The air force plane travelled for a total of 6.9 hours.

<u>SOLUTION: </u>

Given, An Air Force plane left Nairobi and flew west at an average speed of 159 mph.  A cargo plane left sometime later flying in the same direction at an average speed of 207 mph.  After flying for 5.3 hours the cargo plane caught up with the Air Force plane.  

We have to find the number of hours the Air Force plane flew before the cargo plane caught up.

Now, we know that, \text { distance travelled }=\text { speed } \times \text { time }

For air force plane \rightarrow \text { distance travelled }=159 \mathrm{x} \text { time taken by air force plane }

\text { For cargo plane } \rightarrow \text { distance travelled }=207 \times 5.3 \text { hours }

Now, when cargo plane caught the air force plane the distance travelled by the planes will be equal.

So, 159 \times \text { time taken by air force plane }=207 \times 5.3

\Rightarrow =\frac{207 \times 5.3}{159}

\Rightarrow =\frac{1097.1}{159}

Time taken by air force plane = 6.9  hrs
