Answer:
(x−2)(x−4)
Step-by-step explanation:
Let's factor x2−6x+8
x2−6x+8
The middle number is -6 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -6
Multiply together to get 8
Can you think of the two numbers?
Try -2 and -4:
-2+-4 = -6
-2*-4 = 8
Fill in the blanks in
(x+_)(x+_)
with -2 and -4 to get...
(x-2)(x-4)
Hope this helps! Also, if it's no trouble, can I have brainliest? Thanks! :D
Hello!
To solve this, find the cost of a single light bulb first, by dividing 9 / 5.
9 / 5 ==> 1.80
One light bulb is $1.80
Now, multiply 1.80 by 7.
1.80 * 7 = 12.6
7 light bulbs cost $12.6
Hope this helps! ☺♥
Umm sorry i do not know that answer I am just getting the points for again so so so sorry ;(
I wrote down the answer cuz it’s just easier to read that way:)
Answer:
g(f(x)) = x² + 6x + 9
General Formulas and Concepts:
<u>Algebra I</u>
- Composite Functions
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² + 6x + 7
g(x) = x + 2
g(f(x)) is x = f(x)
<u>Step 2: Find g(f(x))</u>
- Substitute: g(f(x)) = (x² + 6x + 7) + 2
- Combine like terms: g(f(x)) = x² + 6x + 9
