Answer:
257 is prime.
Step-by-step explanation:
To evaluate if a number is prime, we just need to evaluate it for the prime numbers that are equal or lesser than the said number's square root.
In this case, √257 = 16.03 so we just need to see if 257 is divisible by <u>2, 3, 5, 7, 11 and 13</u> (the prime numbers that come before 16)
- 257 is odd, so it is not divisible by 2.
- The sum of its digits is 14, therefore, it is not divisible by 3.
- 257 ends in 7, therefore it's not divisible by 5.
- 257/ 7 = 36.71 so it's not divisible by 7.
- 257/ 11 = 23.36 so it's not divisible by 11
- Finally 257 / 13= 19.76 so it's not divisible by 13.
Therefore, 257 is prime.

C multiply 1/2 by 10 and 1/5 by 2
The computation shows that the area of the kitchen that's in the home in square feet is 50ft².
<h3>How to calculate the area?</h3>
It should be noted that an area of a rectangular space is calculated by multiplying the length by the width.
In this case, the area of the kitchen will be:
= 5ft × 10ft
= 50ft²
