If by this you mean perpendicular bisectors, then they would intersect at one point.
Answer:
2.5L of 10% salt solution and 7.5L of the 30% salt solution
Step-by-step explanation:
let the amount of L in the 10% solution be 'x'
let the amount of L in the 30% solution be '10-x'
* because they add up to a total of 10L
10%(x) + 30%(10-x) = 25%(10)
0.1x + 3 - 0.3x = 2.5
-0.2x = -0.5
x = 2.5
x =2.5
10-x = 7.5
2.5 of 10% solution and 7.5% of 30% solution

Answer:
(x-3) is the correct expression
Step-by-step explanation:
To factor you split the expression apart -
x² + 2x – 15
This breaks up to (x+5)(x-3)
If you multiply (FOIL) these you get your expression x² + 2x – 15
Your answer choices do not include (x+5) so it must be (x-3)
