YZ=a+8
Can someone help me ASAP..IM SO CONFUSED

Answer 1

HELPPPPPPPPPPPP!!!!!!!!!!!!!

Answer 2

PLEASE!

Answer 3

Is there a diagram?

Answer 4

That's a LOT better.

So XZ = XY + YZ right?

You are given:
XZ = 50
XY = a
YZ = a + 8

So if you plug them into our equation:

50 = (a) + (a + 8) <--understand?
50 = a + a + 8 <-- Since it's addition, parentheses don't matter (Associative)
50 - 8 = a + a + 8 - 8 <-- subtracting 8 to BOTH sides, so it's still equal.
42 = a + a <-- simplified
42 = 2a <-- combining 'like-terms'
42/2 = 2a/2 <-- dividing BOTH sides by 2, so it's equal
21 = a <-- simplifying.

So now that you know a = 21
XY = a
YZ = a + 8

Can you figure it out now?
