Answer:
The third one :)
Step-by-step explanation:
This can be factored into (x+9)(x+5)/(x+9)(x+1)
once simplified, it's (x+5)/(x+1)
The denominator cannot be negative, so x≠-1
Therefore, the answer is C.
Answer:
1487.1 centimeters
Answer:The amount of commission made is 144
Step-by-step explanation:
The department store worker gets paid 325.00 per week plus 4% commission of their total sales. This means that the worker's earning is not fixed. It varies with the amount of sales made
if the worker sells 3600 of the merchandise, it means that the worker's sales commission will be 4% of 3600 of the merchandise
Sales commission earned by the store worker = 4/100 × 3600
= 0.04 × 3600 = 144
We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.
Distribute and multipy out:
(x − 9)(x − 1)
x * x = x²
x * -1 = -x
x * -9 = -9x
-9 * -1 = 9
Add together:
x² + -x + -9x + 9
x² − 10x + 9
Use the Reflexive property:
x² − 10x + 9 = x² − 10x + 9 ✓
