What is the coefficient of the c-term of the algebraic expression 14a-72r-c-34d?
a. -34
b. -1
c. 0
d. 1

Option B. -1

Step-by-step explanation:

we have

we know that

The coefficient of a term is equal to the number that multiply the term

so

In this problem

14 is the coefficient of the a-term

-72 is the coefficient of the r-term

-1 is the coefficient of the c-term

-34 is the coefficient of the d-term

therefore

-1 is the coefficient of the c-term

4

step-by-step explanation:

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
