ALGEBRA 1
lukranit [14]

The main thing about a polynomial is it's the sum of terms, each a constant coefficient times whole number power (0, 1, 2, 3, ...) of the variable.

A. 35x² is a polynomial; the power 2 is a whole number.  There's only one term so not really the sum of terms, but one's enough.  

B. 4x + x \sqrt{-1} = (4+i)x

That's a perfectly good polynomial but you might not have gotten to it in algebra I yet.  The square root of negative 1 is abbreviated <em>i</em> and when we add it to the set of real numbers we get complex numbers.    It has a complex coefficient 4+i but that's OK in a polynomial.

If you haven't gotten to complex numbers yet you might be expected to answer no to this one.  I don't know.

C.  7x^7 - x^{-5}

The negative exponent means this isn't a polynomial.

D. x/5 + 2

That's fine, just another way of writing

\frac 1 5 x + 2

which is a perfectly ok polynomial.

Answer: A B D

At 2:30 p.m., Cayson leaves his house and drives north to the stadium. He arrives at
STatiana [176]

It takes Cayson 2.5 hours to get from house to the stadium and it takes Riley 3 hours to get from house to the lake. In total they spent 5.5 hours to overcome the distance 385 mi.

Use formula:

D=rt, where D is distance, r - speed and t - time.

Thus,

385=r\cdot 5.5,\\ \\r=70 mi/h.

Answer: 70 mi/h.
