Answer:
Jane: 37 years old
Anne: 17
Step-by-step explanation:
Jane 12 years ago: 5x
Anne 12 years ago: x
In three years into the future:
Jane: 5x+15
Anne: x+15
CURRENT TIME:
Jane: 5x+12
Anne: x+12
Equation (using 3 years into the future ages): 5x+15=2(x+15)
5x+15=2x+30
(subtract 15 from both sides)
5x=2x+15
3x=15
x=5
Therefore, Jane is 37 years old and Anne is 17 years old.

Answer:
884cm^2
Step-by-step explanation:
top triangle area=21*24/2=252
central triangle area=16*24/2=192
left n right triangle area (each)=22*20/2=220
total area of wood needed=252+192+220+220
=884cm^2
Domain is all Real Numbers and Range is from 0, but not including 0, to infinity. So it would be the first one
