Question

A stick is cut into three pieces of lengths (7x - 2y +3z) cm. (y - 3x +7z) cm and
(z-3y + x) cm. Find the original length of the stick.​

Answer 1

Answer:

as it cut into 3 pieces

it's original length is sum of cutted lengths

original length = (7x - 2y +3z)+(y - 3x +7z)+(z-3y + x)=(5x-4y+11z)cm

Answer 2

Answer:

Step-by-step explanation:

given,

stick has been cut= 3 pieces

length of 1= (7x - 2y +3z) cm

length of 2= (y - 3x +7z) cm

length of 3=(z-3y + x) cm

So,

 total length of stick= (7x-2y +3z)+ (y-3x +7z)+ (z-3y+x)

grouping on the bases of terms= 7x-3x+x + (-2y)+y(-3y) + 3z+7z+z

therefore we get,

total length of stick =5x-4y11z
