Answer:
5
Step-by-step explanation:
The distance is given by sqrt((-3-0)^2+(-3-1)^2)=sqrt(9+16)=5
U = -b + 21 . . . (1)
u = -2b + 30 . . . (2)
Equating (1) and (2),
-b + 21 = -2b + 30
-b + 2b = 30 - 21
b = 9
u = -9 + 21 = 12
Therefore, (b, u) = (9, 12).
Answer: 4x - 13
<h2>
Step-by-step explanation:
</h2>
<em>First, we need to get triple of x:</em>
Triple of x is: 3x
<em>Next is to get the difference between 3x and 13:</em>
x + 3x -13
4x - 13
Hence, the variable expression is 4x - 13
