Which expression is monomial?
a. 1/x
b. 3x^.5
c. x+1
d. 7

D) 7 is monomial.

Step-by-step explanation:

Given : Monomial options .

To find : which expression is monomial.

Solution : We have given options

Monomial  : Which has only one term with constant or positive exponent .

Then

7 is only the monomial .

All other polynomial has negative power and fractional power so, it would not be monomial .

X + 1 has two terms so it would also not a polynomial.

Therefore, D) 7 is monomial.

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees
