What is a prime or composite number?
melomori [17]
-A prime number is a whole numbergreater than 1, whose only two whole-number factors are 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.

- A whole number that can be divided evenly by numbers other than 1 or itself. Example: 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is acomposite number. But 7 cannot be divided evenly (except by 1 and 7), so is NOT a composite number (it is a prime number).

A triangle has sides with lengths of 48 meters, 51 meters, and 31 meters. Is it a right triangle?
Genrish500 [490]

Answer:

Step-by-step explanation:

Formula = a^2 + b^2 = c^2

Putting values

= (31)^2 + (48)^2 = (51)^2

= 961 + 2304 = 2601

= 3265 = 2601

Both sides are not equal so it is not a right triangle

GarryVolchara [31]

Answer:

-9A · √(5yA)

Step-by-step explanation:

The coefficient -3 stays the same.

45 factors into 5·9, which is helpful because 9 is a perfect square.

Thus, √45 = 3√5.

y cannot be factored.  It stays under the radical.

A³ can be factored into A² (a perfect square) and A.

Thus,

-3√(45yA³) = -3 · 3√5 · √y · A · √A, or

                   = (-3)(3)(A) · √(5yA), or

                    = -9A · √(5yA)
