Sum of polynomials are always polynomials.
Note that despite it's name, single constants, monomials, binomials, trinomials, and expressions with more than three terms are all polynomials.
For example,
0, π sqrt(2)x, 4x+2, x^2+3x+4, x^2-x^2, x^5+x/ π -1
are all polynomials.
What makes an expression NOT a polynomial?
Expressions that contain non-integer or negative powers of variables, rational functions, infinite series.
For example,
sqrt(x+1), 1/x+4, 1+x+ x^2/2!+x^3/3!+x^4/4!+...., (5x+3)/(6x+7)
are NOT polynomials.
C is the cost of groceries.
if there is 5% discount, then the current price = 100% - 5% = 95%
= 95% of c
= (95/100) * c
= 0.95c
The formula for compounded interest is A = P (1+r/n)^nt.
P=580
r = .09
n = 1
t = 9

A = 1259.698 is how much the balance will be. (Rounded to 1259.70 if you round to the nearest cent).
Answer:
∠ e = 40°
Step-by-step explanation:
Since Δ ABC and Δ EDC are congruent then corresponding angles are congruent, that is
∠ A = ∠ E = 40°
