Answer:
nth term = 18 - 3n
Step-by-step explanation:
nth term = a + (n - 1)d
a1 = 15
d = -3
nth term = a + (n - 1)d
= 15 + (n - 1)-3
= 15 + (-3n + 3)
= 15 - 3n + 3
= 18 - 3n
nth term = 18 - 3n
For instance, if you want to find the 10th term
nth term = 18 - 3n
10th term = 18 - 3(10)
= 18 - 30
= -12
10th term = -12
Unlike terms I guess meaning a zero pair?
Here are some examples of how the Quadratic Formula works:
<span>Solve <span>x2 + 3x – 4 = 0</span></span>
This quadratic happens to factor:
x2 + 3x – 4 = (x + 4)(x – 1) = 0
.
Then, as expected, the solution is <span>x = –4, x = 1</span>.
Answer:
1728/ 125
Step-by-step explanation:
The ratio of corresponding lengths of the figures = ratio of the square root of their areas.
So ratio of lengths = 12/5.
Now volume is 3 dimensional so the ratio is the cube of the lengths
= 12^3/5^3
= 1728/ 125.
Answer:
x ≥ 3.
Step-by-step explanation:
A minimum of 3 means 3 or more than 3, so it's
x ≥ 3.
