(A) x
(B) x + 6
(C) 6x + 18
(D) 2x + 6
(E) 3x + 5
Answer:
If integer m is not a multiple of 3, which of the following must be true? ... of 2 let m=3K+2, (m+1)(m-1) = (3K+3)X(3K+1) is a not a multiple of 2
Step-by-step explanation:
m=4 or 5 satisfies the equation (m+1)(m-1) is a multiple of 3. Hence true.
m=4, (m+1)(m-1) = (4+1)(4-1)=15, not multiple of 2.
Answer:
22
Step-by-step explanation:
x+x+2+x+4+x+6+x+10
126
x=16
16+6=22
Answer:
The highest common factor of 30 and 45 is 15.
Step-by-step explanation:
factors of 30 = 1, 2, 3, 4, 5, 6, 10, 15, 30 ; factors of 45 are = 1, 3, 5, 9, 15, 45)
Greatest common factor is 15
Answer:
15.
Step-by-step explanation:
HCF is also called GCD. So, you divide both numbers with a common number that can divide both numbers at the same time without a remainder.
3 30 45
5 10 15
2 3
3 × 5 = 15
