Answer:
True.
Step-by-step explanation:
We can represent an odd number by 2n + 1 where n = 0, 1, 2, 3, 5 etc.
Substituting:
a^2 + a = (2n + 1)^2 + 2n + 1
= 4n^2 + 4n + 1 + 2n + 1
= 4n^2 + 6n + 2
= 2(2n^2 + 3n + 1)
which is even because any integer multiplied by an even number is even.
This is also true if we use a negative odd integer:
We have 4n^2 + 4n + 1 - 1 - 2n
= 4n^2 + 2n
= 2(2n^2 + n(.
Answer:
323 mod 5 = 3
−323 mod 5 = -3
327 mod 3 = 0
(64 * (-67) + 201) mod 7 = 6
(38^12) mod 6 = 4
(38^12) mod 3 = 1
Step-by-step explanation:
The modulo operation looks for remainders from the quotients. In order to find them, divide the whole number by the mod number. Then take just the decimal after the whole answer and multiply it by the mod number.
<u>323 mod 5</u>
323/5 = 64.6
.6 * 5 = 3
<u>−323 mod 5</u>
323/5 = -64.6
-.6 * 5 = -3
<u>327 mod 3</u>
327/5 = 109
0 * 3 = 0
<u>(64 * (-67) + 201) mod 7</u>
64 * -67 = -4288 + 201 = 4087
4087/7 = 583.85714
.85714 * 7 = 6
<u>(38^12) mod 6</u>
38^12 = 9.07x10^18
9.07x10^18/6 = 1510956318082499242.6666667
.666667 * 6 = 4
<u>(38^12) mod 3</u>
38^12 = 9.07x10^18
9.07x10^18/3 = 3021912636164998485.333333
.3333333 * 3 = 1
About 1.88 meters. One meter is 3.28 feet
= 9 * 10^5 * 3 * 10^10
= 27 * 10^5 * 10^10
= 27 * 10^15
= 2.7 * 10^16 - The best selection appears to be the first option.
Good luck :)
