Answer:
what is the quistion
Step-by-step explanation:
X^2 + 8x + 16 =
(x + 4)(x + 4) or (x + 4)^2
For perimeter you just add the sides up, so 15+12+9 which = 36
X/y = 2 so x = 2y
z/x = 4 so z = 4x but x = 2y so z = 4(2y) = 8y
now you have
x = 2y, z = 8y
x + y + z 2y + y + 8y 11y 11
------------ = -----------------------= ------------- = ----------- = 5 1/2
x 2y 2y 2
answer
C. 5 1/2
Hey there! :D
All parallel lines have the same slope. They would need to, otherwise, they would intersect or come together at an angle eventually.
So, let's find the slope.
I'm going to use rise over run. (Remember, when moving to the left, you make the number negative.
rise=1 run= -3
-1/3 <== the slope
"C" is the correct answer.
I hope this helps!
