10x^2-10x+20 is the answer to this
Answer:
||u|| = sqrt((0 + 3)^2 + (4 + 2)^2) = 6.71
||v|| = sqrt((3 + 0)^2 + (3 + 2)^2) = 5.83
slope of u = 4/2 = 2
slope of v = 5/3
=> Option D is correct
Hope this helps!

PQ is bisected by line <em>L</em>.
so the answer is C
PQ=14
Step-by-step explanation:
5x-3=11-2x
5x+2x=11+3
7x=14
x=2
replace X in any of the given distance equation then multiply by 2 since the distance Pm=Qm
PQ=2(11-2x)
2(11-2(2))
2(7)
Therefore PQ=14
Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
You just find the numbers that you can multiply to get -28
