Answer:
So x = 20
Step-by-step explanation:
AB + BC = AC sum of a segment is sum of its pieces
AB + AB = AC B is the midpoint, so AB = BC
2x + 2x = 3x + 20 putting in for AB (twice!) and AC
4x = 3x + 20 collect like terms
x = 20 subtract 3x on both sides.

Answer:
Not really 100% sure how to answer this, but if you would like to find the price of any item 10% off, you would just multiply the price by 0.9
EX: item cost $100

Answer:
D
Step-by-step explanation:
Terms are separated by addition and subtraction symbols.
Polynomials consist of terms that are constant and/or variable. The variable terms must have 0 or positive exponents. Polynomials will not consist of division of variable expressions.
Examples of polynomials:
Examples of non-polynomials:
In general a polynomial when written in standard form should be comparable to:
where the 
's could be zero and all the exponents,n, are positive or 0.
D is comparable since all of these are 0 except 
which is 1 and 
which is -2.
Also the other choices have either division by variable expressions and/or negative exponents on variables.
