2. The length of XZ is 28 units. If XY = 2x + 2 and YZ = 9x – 7, what are the lengths of XY and
Novosadov [1.4K]

Answer:

XY = 8 and YZ = 20

Step-by-step explanation:

If XY and YZ are on the one line, we can write

XY + YZ = 28

(2x+2) + (9x - 7) = 28

2x+2 + 9x - 7 = 28

11x - 5 = 28

11x = 33

x = 3

XY = 2x+2 = 2*3 + 2 = 8

YZ = 9x - 7 = 9*3 - 7 = 27 - 7 = 20

It’s possible to build a triangle with side lengths of 5,5, and 10
nikitadnepr [17]
No.  The two lengths 5 and 5 add up to 10; you'd have two sides of length 5 each placed end to end, equaling 10.  That'd be represented by segments on a straight line, not a triangle.

Hope you've drawn a picture, so as to understand this better.  ;)
