Write the expression that represents the total length of each segment shown.

Step-by-step explanation:

a) Total length = x + 1

b) Total length = d + 4

c) Total length = y + 3

see below

Step-by-step explanation:

To find the total length, add the length of the parts

For the segment on the left

x+1

For the middle segment

d+4

For the segment on the right

y+3

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
