Classify the following polynomials according to the number of terms. Combine any like terms first.
11Alexandr11 [23.1K]

1) Combining like terms, we get x^2 + 5x, which is a binomial.

2) Combining like terms, we get x^3 + 3x^2, which is a binomial.

3) Combining like terms, we get 4x^3 + x^2 - x, which is a trinomial.

4) I can't answer this because there's an asterisk in place of the exponent.

Please help! I'm getting timed.
Molodets [167]
Hi there! The answer is A.

t = 2(s + 2)
To get a proper idea of the type of function this formula represents we work out the parenthesis.

Working out the parenthesis can for instance be done using rainbow technique.
t = 2s + 4

We can now see sinilarities between this function an the general function of a line in slope intercept form
y = mx + n

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
