"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like
.
A binomial has 2 terms like 
A trinomial has 3 terms like 
And a polynomial has 4 or more terms.
So basically one can classify the type of polynomial by counting the number of terms in a given equation.
Hi!
To solve exponental equations, multiply the exponents.
4·5=20
The answer is

Hope this helps! :)

9 x 400 + 9 x 70 + 9 x 5. (9 x 470) + (9 x 5).
1 dozen cost 5.98
so 1.5 dozen cost : 5.98 x 1.5 = 8.97
a coupon takes $1 off the price so
8.97-1.00 = 7.97
they cost a total of $7.97
we are given with an angle of 3 pi over 4. As we convert this to degrees, we can see that it is equivalent to 135 degrees and is a second quadrant angle. when y-coordinate is equal to 1, we can find the point on the terminal side or the x-xis by using tan theta. tan theta is equal to y/x. x then is equal to -1.
