Prime numbers are numbers that can be divided without a remainder. So 2181 is divisible by 3 and 727 and there is no remainder.
Answer:
< 3, < 5
Step-by-step explanation:
< 3 is congruent to 36° due to the vertical angles rule which says that any angle across form each other is congruent
Answer:
17
Step-by-step explanation:
Let x represent the smaller integer. Then we have ...
(x +1)² +(x +2)² = 40x +5
2x² +6x +5 = 40x +5
x² -17x = 0 . . . . . subtract (40x+5), divide by 2
x(x -17) = 0 . . . . . factor
The solution of interest is x = 17.
The smaller integer is 17.
For this case we must solve the following equation:
We remove the parentheses on the right side:
We add similar terms on the right side:
We subtract 
from both sides of the equation:
We add 9 to both sides of the equation:
We divide by 8 on both sides of the equation:
We apply square root to both sides of the equation:
We have two roots:
