Answer:

Step-by-step explanation:

Let's start by prime factorizing (finding the prime factors) of 16 and 21:

$16=4*4=2*2*2*2=2^4$

$21=3*7$

We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.

Gwar [14]

Answer:

The slope is 2

Step-by-step explanation:

To find the slope given two points, we use the formula

m = (y2-y1)/(x2-x1)

= (-4--2)/(2-3)

= (-4+2)/(2-3)

= -2/-1

= 2

Find X Options: 6 4 square root 6 6 square root 146

For this case we can apply the Pythagorean theorem to find "x". Taking the rectangle triangle of base 5 we have:

$x = \sqrt {11 ^ 2-5 ^ 2}\\x = \sqrt {121-25}\\x = \sqrt {96}\\\x = \sqrt {4 ^ 2 * 6}$

By definition of power properties we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$x = 4 \sqrt {6}$

Answer:

$x = 4 \sqrt {6}$

Marat540 [252]

Answer:

-1

Step-by-step explanation:

first put the equation in slop int form:

y= x-6

to find the slope of a line that is perpendicular take the negative reciprical of the slope

so the answer is

-x
