290 m2 you just have to add all of them
They each ate 1.5 pieces of pie
Answer:
x=19
DE=84
EF=36
reasoning:
the sum of DE and EF is 120, so to find the value of each first you find x
find x by adding DE and EF
this gives you the equation (4x+8)+(2x-2)=120
combine like terms and get 6x+6=120
subtract 6 from both sides to get 6x=114
divide both sides by 6 to get x=19
plug 19 into x in both equations to get the values of each length
