Answer:
3(5n-6)
Step-by-step explanation:
You want to find the common multiple between the two numbers.
Find a number that is divisible by both numbers, and to find that, you need to factor them out using multiples that are suitable for each number
15:
5 x <u>3</u>(only multiple pair that has whole numbers)
18:
9 x 2(no)
6 x <u>3(yes)</u>
After you have found your answer insert it into the equation.
3(5n-6)
To check if you're right, multiply 3 into the brackets and you will get your answer.
3 x 5n - 3 x 6
15n-18

A vertex can be the max or min. The vertex is the highest point or lowest point of a function.
Answer:
1/2ft
Step-by-step explanation:
15/28=(5/7)(1 1/2)(w)
15/28=(5/7)(3/2)w
15/28=(15/14)w
(15/28)/(15/14)=w
(15/28)*(14/15)=w
w=14/28
w=1/2 ft
One clock of any type costs $3.20. a clocks cost 3.2a. w clocks cost 3.2w.
Add 3.2a to 3.2w to find the total cost.
T = 3.2a + 3.2w
T = 3.2(a + w)
Both expressions above are correct answers.
