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)

Answer:
Each person will get 
of the whole package of pencils.
Step-by-step explanation:
Since we know that 3/8 of the package was divided among 3 people we just have to divide 3/8 by 3 in order to find out what fraction of the whole package of pencils each person will receive. And so we get...
÷ 3 =
Therefore, each person will get 1/8 of the whole package of pencils.
Area=pi r squared
area=3.14 x 10squared
area= 314

Answer:
a = 1/2
Step-by-step explanation:
a - 3/10 = 1/5
Add 3/10 to each side
a - 3/10 +3/10 = 1/5+3/10
a = 1/5+3/10
Get a common denominator
a= 1/5*2/2 +3/10
a = 2/10 +3/10
a = 5/10
Divide the top and bottom by 5
a = 1/2
