1) False
2) You can use the equation
y = mx + b
m = -2/3
y = (-2/3)x + b
Now you need the b value, but there is not enough info to find that.
What do the parts (A) and (b) represent?

ok. so that you've A, B=2A (considering its two times as lengthy) and C = 2bef27f3ca803166b8f8249a988a91A+3 (considering its 3 inches more effective than 4x5 cases the first piece). consequently: 38 = A + 2A + 2bef27f3ca803166b8f8249a988a91A + 3 (considering all of them might want to upload as a lot as 38) subtract the three and upload like words and also you get 32bef27f3ca803166b8f8249a988a91 = 7A divide each and every side with the aid of seven and also you get 4x5=A. So the first piece is 4x5, the 2d piece is 10 (2 cases the first piece) and the perfect piece is 23 ( [2bef27f3ca803166b8f8249a988a912bef27f3ca803166b8f8249a988a912bef27f3ca803166b8f8249a988a91] + 3). 1st piece = 4x5 second piece = 10 third piece = 23
