i'm not sue whether to simplify it or solve x and y but when you simplify it you get 2x+2y+2z if thats not what you want then you could ask me for what you acctually want
simplfy the fist equation to get a^2+4a=-21 and it can also be (a+4)a=-21 so we get a=-3 since 3+4=7 and -3*7=-21 then we plug a=-3 into the second equation to get 81-(-27)+9=3n which is 117=3n so n=39
so A=7 B=5 since we get the equation (A+1)=2(B-1) and A-1=B+1 so find that A has 2 more than B from the second equation and find that B=5 when we plug that into the first equation and when B=5 then A=7
So since there are 59 jobs we do 59+1/2=30 and the 30th one has $23000 so the median value is 23000
a=1 b=6 and c=4 since it has to be a number between 0 and 6 so the only way is 49-42+4=11 and that makes a=1,b=6, and c=4
Well I simplified it into (82+18)^2 and I used variables like a=18 and b=82
You just forgot to add another 0 at the end
it's 1,000,000
x=-50 since we take the +6 on the right side and mak it a -6 on the lft side to become -10=x/5 and tak the /5 on the right side and make it a *5 to get -50=x so x=-50
the area is 1 1/2 or 1.5 becuase you are basicly divideing it into th halvs of the 4 squares that you made so I got 1/2 or 0.5 and you subtract 1 of those triangles and 2 of the squares so the area is 4-2-0.5=1.5=1 1/2=3/2
