What is the describes the number 5? write prime composite neither prime nor composite or both prime and composite

prime is your answer

have a nice day stranger

Prime. Whether a number is prime or composite depends on whether or not you can "break it down" by multiplication. Primes are the building blocks of the counting numbers in the sense that any number can be written in the form of one or more primes multiplied together. We call numbers created with two or more primes in this way composite, and we leave the number 1 out of the discussion as a number that's neither prime nor composite.

5 only has 1 building block: 5. It is a building block.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
