2⋅(4⋅a)
8a
Step-by-step explanation:
(4⋅a)⋅2
4⋅(a⋅2) This is the same by the associative property of multiplication
2⋅(4⋅a) This is the same by the associative property of multiplication and the communicative property of multiplication
4⋅2⋅a⋅2 This brings in an extra 2 so it is not the same.
8a 4*2 = 8 so this is the same
4⋅2+a⋅2 This is the not the same 8+2a is not the same as 8a
Answer:
2.3
Step-by-step explanation:
on the left side u add 4k+3k=7k
on the right side u subtract 2k-6k=4k
then on the left side u add 2 to each side and u get rid of the 2 on the left side
on the right side u add 5+2=7
then on the right side u add 4k on each side and get rid of the 4k on the right
on the left u subtract 7k-4k=3k
on both sides divide by 3
