7500
the way is multiply the length value by 1000
For the lcm u should make a list for gcf you should do a factor tree
Answer:
26
Step-by-step explanation:
3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x )
3x-9 = 5x-4 + 21 - 3x
collect like terms
3x-9 = 2x +17
move the terms
3x-2x = 17+9
x=26
(4x+4y)+(8x+8y)
12x+12y
That should be your answers, you can't add them bc they're not like terms.
