Answer:
So the greatest common factor 15 and 21 is 3.
Step-by-step explanation:
Answer:
a. a straight line passing through the origin
Answer: n = 1, n = -1/3
<u>Step-by-step explanation:</u>
(3n - 1)² = 12n + 8
9n² - 6n + 1 = 12n + 8
9n² - 18n - 7 = 0
Substitute -18n with 3n - 21n and find the common factor of each side:
9n² + 3n -21n - 7 = 0
3n(<u>3n + 1</u>) -3(<u>3n + 1</u>) = 0
(3n - 3) (3n + 1) = 0
Solve for each factor:
3n - 3 = 0 3n + 1 = 0
3n = 3 3n = -1
n = 1 n = -1/3
Answer:12 (2v-7)
Step-by-step explanation: You have to find The GCF which is 12.THen you do 24v divide 12 which is 2v and do 84 divide 12 which is 7.Now put GCF which is 12 ,then write (,next write 2v - 7 .
Hope it helps :)
The answer is x equals 2.
