Why could I write 10 + 10 + 8 + 8 as (10*2) + (8*2)? answer 1 Because adding a number together twice is the same thing as multiplying the number by 2.

answer 2 Because 2 is a factor of both 10 and 8

yes

Step-by-step explanation:

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
