4+9+14+...+494
d=9-4=5
\[a_{n}=a_{1}+(n-1)d\]
Answer:

Step-by-step explanation:
<u><em>Let's check it using Pythagorean Theorem:</em></u>

Where c is the longest sides, a and b are rest of the 2 sides
1) 9 , 40 , 46
=>
=> 
=> 2116 = 81 + 1600
=> 2116 ≠ 1681
So, this is not a Pythagorean Triplet
2) 16, 30 and 34
=> 
=> 
=> 1156 = 256 + 900
=> 1156 = 1156
No need to check more as we've found the one which is not a Pythagorean Triplet.
The measure of arc XZ is equal to the measure of the corresponding central arc, which is 45 degrees. So the measure of arc XZ is 45 degrees. I learned this last year in math. I hope this helps.
Answer:
Given the statement: The quotient of a number x and 4 is atmost 5.
Let x be a number.
"quotient of a number x and 4" represented as 
"at most" means '
'
Therefore, the inequality for the given statement is;

Solve the above inequality:

multiply both sides by 4 we get;

Simplify:

Therefore, the solutions for the given inequality is: ![(-\infty , 20]](https://tex.z-dn.net/?f=%28-%5Cinfty%20%2C%2020%5D)
