Answer:
- 3 and 5 if "." marks thousands
- 2, 3, 5, 6 if "." is a decimal point
Step-by-step explanation:
The number 2145 is not even, so will not be divisible by 2 or 6. It ends in 5 so is divisible by 5. Its sum of digits is 12, which is divisible by 3, so the number is divisible by 3.
2145 is divisible by 3 and 5.
2.145 is divisible by all of these numbers:
2.145/2 = 1.0725
2.145/6 = 0.3575
2.145/5 = 0.429
2.145/3 = 0.715
_____
Here, we take the mixed number to be divisible if the decimal representation of the quotient is a terminating decimal fraction.
Answer:
21
Step-by-step explanation:
prim factors: 2, 3, 5, and 11
Answer:
From my knowledge and my research the answer is B! Thank you
Step-by-step explanation:
hope this help Answer:( x - 3i√2)(x + 3i√2)
solve x² + 18 = 0
x² = - 18 ⇒ x = ±√- 18 = ±3i√2
factors are ( x - (3i√2))(x - (-3i√2))
x² + 18 = (x - 3i√2)(x + 3i√2
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
This involves the Secant and Segments Theorem.
8(19 + 8) = 9(9 + x)
216 = 81 + 9x
9x = 135
x = 15
