Answer:
7, 9, 11
Step-by-step explanation:
x+x+2+x+4=5(x+2)-18
3x+6=5x+10-18
3x+6=5x+-8
3x=5x+-14
-2x=-14
x=7
Let
x-------------> <span>original price of the skates
we know that
15% of x is </span><span>$19.50
so
0.15x=19.50---------> x=19.50/0.15-----------> x=$130
the answer is
the </span>original price of the skates was $130<span>
</span>
Answer:
Step-by-step explanation:
If the polynomial function has zeros at 9 with multiplicity 1, then 
is a factor of the polynomial.
Also if the polynomial function has a zero at 
with a multiplicity of 2, then
is another factor of the polynomial.
The polynomial function can therefore be written as;
But the given polynomial has an 
value of 2, hence the required polynomial is
F(n) = 237 − 0.7 × f(n − 1) + 50, f(0) = 235, n > 0
