The subtraction of the polynomial (19xy + 3y - 28) - (- 15xy - 2y - 15) is 34xy + 5y - 13
<h3>How to subtract polynomial</h3>
Given:
(19xy + 3y - 28) - (- 15xy - 2y - 15)
= 19xy + 3y - 28 + 15xy + 2y + 15
= 19xy + 15xy + 3y + 2y - 28 + 15
= 34xy + 5y - 13

Answer:

Step-by-step explanation:
Divide n by 100,000.
This gives us the "number of times 100,000 fits in n", or, "how many 100,000's n is", or as the hint says, "how many times larger n is than 100,000".
All represented by this formula:

Answer:
C
Step-by-step explanation:
So, there are 16 ounces in a pound.
There are 3 1.2, or 3.5 pounds.
To find the total ounces, lets multiply the ounces per pound by the total amount of pounds:
16*3.5
=
56
So your answer is 56!

ax^2 +bx+c=0
X^2 + 2x+8=0 so a=1, b=2, c=8
Discriminat= b^2 -4ac=2^2 -4•1•8=4-32=-28
So there are no real number solutions, yet there are complex numbers solutions.
Solutions=(-b+- sqrt (discriminant))/2•a
=(-2+-i sqrt ( 2•2•7))/2
Solutia 1= -1 + i sqrt7
Solutia 2= -1 - i sqrt 7
Answer:
X=10
AB=12
BC=27
Solution: solving the algebraic equation we get x=10, then plug in x for each of the equations separately
