Y = k/x
5 = k/8
k = 5 x 8 = 40
Therefore,
y = 40/14 = 2.86

Answer:
10
Step-by-step explanation:
By Pythagoras' Theorem:
16 + r = √(24^2 + r^2)
(16 + r)^2 = 24^2 + r^2
256 + 32r + r^2 = 576 + r^2
32r = 320
r = 10
Answer:
Step-by-step explanation:
is essentially 
(you are squaring 
, so multiplying it by itself), so to simplify, you would need to distribute.
A good way to go about this is using the F.O.I.L. method, multiplying the First numbers in the parentheses, then the Outers, then Inners, and finally, Lasts.
>> 
>> 
>> 
(
)
After doing so, you would end up with 
, and after combining like terms, 
.
To write the expression in standard form, though, just order the terms from highest to lowest power!
