4x^2 + 16x-2= 5x
Minus 16x over
4x2-2= -11x
Add 11x over
4x^2 +11x -2
Use quadratic formula x= 2.9
I’m not sure here. I tried my best. Hope it helps!

Answer:
4/15
Step-by-step explanation:
Bag A
3 red marbles and 6 blue marbles. = 9 marbles
P(blue) = blue/total =6/9 = 2/3
Bag B
6 green marbles and 4 yellow marbles. = 10 marbles
P(yellow) = yellow/total=4/10 = 2/5
P(blue,yellow) = 2/3 * 2/5 = 4/15
we know that
1) Lily swims a 
-meter race
2) She swims the first half in 
seconds
3) She swims the second half in 
seconds
so
To find the total time to swim the whole race sum the time in the first half plus the time in second half
therefore
<u>the answer is</u>
X=15 and Y=?
X=30 and Y=6
By rule of three
15x6/30 = 3
The answer is Y=3
