8y-6y^2/7^3
Answer:
2
Step-by-step explanation:
You count terms that are seperated by - and + signs. Any type of fraction is considered one term.
So you count 8y as one term and the rest is a whole fraction so you also count that as one term.
You add all the terms together and you have 2 terms in this equation.

If the sum of the first 20 square numbers is 2870 then sum of the first 21 square numbers is 3311.
Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The first square number is 1, and the sum of the first 20 square numbers is 2870.
We need to find the sum of the first 21 square numbers.
for first 20 numbers the answer is
n(n+1)(2n+1)/6
20*21*41/6 = 2870
Now we have to find the sum of first 21 square numbers.
21²=441
Now add it with 2870
2870+441=3311
Hence, the sum of the first 21 square numbers is 3311.

Answer: 1, 2, 7, and 14
Step-by-step explanation: The factors of 14 are natural numbers that divide 14 without leaving any remainder. In other words, the factors of 14 divide 14 evenly.
Example: 7 is a factor of 14 because when we divide 14 by 7, it gives us 2 as the quotient and 0 as the remainder. Here, the quotient 2 is also a factor of 14.
So, to check if any number is a factor of 14 or not, divide 14 by that number and verify whether the remainder is zero or not. If the remainder is zero, the number is a factor of 14, otherwise not.
y = 2x + 3?
0.5 - 0.3 = 0.02
0.05 - 0.03 = 0.02
0.05 - 0.03 = 0.2
