NOTES: Find the common factor of the terms and factor it out:
1. Answer: 15r²(3r - 1)
<u>Step-by-step explanation:</u>
45r³ - 15r² <em>they both have 15 and r² as factors</em>
= 15r²(3r - 1)
************************************************************************************
2. Answer: 3x(3x - 1)
<u>Step-by-step explanation:</u>
9x² - 3x <em>they both have 13 and x as factors</em>
= 3x (3x - 1)
************************************************************************************
3. Answer: x(x + 3)
<u>Step-by-step explanation:</u>
x² + 3x <em>they both have x as a factor</em>
= x(x + 3)
The lowest common denominator of 2, 4, 8 is 2 because is the smallest number that can divide all three numbers without any residue.
-1 in decimal form is -1.0, just as 5 in decimal form, for example, is 5.0. Just copy the negative sign.
Answer:
x= 3126/125 or x=25.008 or as a mixed number form: x=25 and 1/125
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
y = 25635 - 3000x
Step-by-step explanation:
I have purchased a new Toyota 4Runner for $25635 and according to the car dealer, the SUV will depreciate in value approximately $3000 per year.
Now, we have to model the situation using y variable as the total value of the car and x variable as the age of the car in years.
So, the equation is
y = 25635 - 3000x (Answer)
