(B) 7 x 10‐³
(C) 7 X 10‐²
(D)7 X 10³

(B) 7 x 10‐³

Step-by-step explanation:

A typical red blood cell in human blood has a diameter of approximately 0.007 mm.

In scientific form = 7 x 10-^3

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
