Area of 4.24 3 3
in a triangle

4.5

Step-by-step explanation:

We can use heron's formula in this case:

let perimeter/2 be represented by

let represent each side length

Heron's formula is as follows:

Plug your numbers into the formula!

=

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
