The first is 6.1 using the distance formula.
distance = sqrt((x2-x1)^2+(y2-y1)^2)
plug it all in and simplify
you get 6.1

the next one is the midpoint. u just take add both values of x together and divide by 2 to get the x coordinate and then add together both values of y and divide by 2 to get the y value. the midpoint is (8,7)

to find the perimeter of the rectangle, add the lengths of each side. 25 for the height and you would add 2 of those and then there are 2 sides as long as the length that you would add. it would be height+height+length+length which is 25+25+77+77=204. remember units so 204 ft

Evaluate the function for the given values to determine if the value is a root. p(−2) = p(2) = The value is a root of p(x).

bija089 [108]

Note: Since you missed to mention the the expression of the function $p(x)$ . After a little research, I was able to find the complete question. So, I am assuming the expression as $p(x)=x^4-9x^2-4x+12$ and will solve the question based on this assumption expression of $p(x)$ , which anyways would solve your query.

Answer:

$p\left(-2\right)=0$

Therefore, $x=-2$ is a root of the polynomial $p(x)=x^4-9x^2-4x+12$

$p\left(2\right)=-16$

Therefore, $x=2$ is not a root of the polynomial $p(x)=x^4-9x^2-4x+12$

Step-by-step explanation:

As we know that for any polynomial let say $p(x)$ , $c$ is the root of the polynomial if $p(c)=0$ .

In order to find which of the given values will be a root of the polynomial, $p(x)=x^4-9x^2-4x+12$ , we must have to evaluate $p(x)$ for each of these values to determine if the output of the function gets zero.

So,

Solving for $p\left(-2\right)$
