The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocal of each other. <span />
To know which of the following expressions are polynomials, let us look at the definition of a polynomial:
Polynomial is derived from poly- (which means "many") and -nomial (meaning "term"), so it says "many terms".
For an instance:
is a polynomial, but
is not a polynomial because it contains single term only.
We must keep in mind that in polynomial it can have variables, constants, and exponents but it can never have division by a variable.
Now lets, look at the
since it has got one term it can not be a polynomial.
: it has got <em>more than one term</em> therefore, <em>it is a polynomial. </em>
: again it has got just one term so it is not a polynomial.
: Since it has got <em>more than one term</em>, so again<em> it is a polynomial. </em>
Answer:
-2, 4
Step-by-step explanation:
a parallelogram is a shape that's lines will never cross, putting the 4th plot there would make that true
Answer:
A. 20mg
Step-by-step explanation:

Cross multiply and divide.
60 × 25 = 1500
1500 ÷ 75 = 20
<em>good luck, hope this helps :)</em>
I would say 60 degrees because the shape that has x is just a bigger version of the original so it would have the same angels so x is 60 degrees
