3x(3x + 2) should be the right answer
Answer:
x = 17
Step-by-step explanation:
Combine like terms first:
x + 3x + 4 = 72 --> 4x + 4 = 72
Isolate the variable by subtracting 4 from both sides so you get
4x = 72 - 4
4x = 68
Divide both sides by 4 to get
x = 68/4
x = 17
Answer:A. - 512
Step-by-step explanation:
Here is how I solved this problem:
-First take -128 and divide it by 16
(You should get -8)
-Then take -8 and cube root it
(You should get 2)
You have found your multiplier, which is 2.
After this you can start from -128 and multiply by 2, 2 times to get to the 8th term which is -512.
me know if you have any further questions.
Answer:
Step-by-step explanation:
Question 1 = 2002
2002 - 2000 = 2 (the years since 2000)
y = (275 x 2) + 50
y = 875
Question 2 = 1425 likes
2005 - 2000 = 5 (the years since 2000)
y = (275 x 5) + 50
y = 1425
Question 3 = 2018
Since y = 5000
5000 - 50(the extra likes) = 4950
4950 / 275 = 18 (the years since 2000)
2000 + 18 = 2018 (the year)
2.434 to 3 sigfigs = 2.43 .
