Anyone know synthetic division?

uranmaximum [27]

Use the rational root theorem
a0=16, an=1

The dividers of a0: 1,2,4,8,16 The dividers of an:1
Therefore check the following rational numbers: +- 1,2,4,8,16/1
4/1 is a root of the expression, so factor out x-4,

compute (x^4+13x^3-64x^2-20x+16)/(x-4) to get the rest of the equation:
x^3+17x^2+4x-4

=(x-4)(x^3+17x^2+4x-4)/x-4

which will leave you with answer B
x^3+17x^2+4x-4

The number of question on an exam varies with the number

alekssr [168]

Answer:

$t=5x$

Step-by-step explanation:

So the number of questions in an exam varies with the number of minutes to take the exam.

For each question there are 5 minutes allotted.

Lets say that there are 'x' number of questions in the exam and 't' is the total time taken to finish the exam, in minutes. So the time taken to complete the exam would be

$5 \times x=5x$

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:

$t=5x$

So there are two variables in the equation, 't', and 'x':

t - time taken to complete the exam

x - number of questions on the exam
