Hey there look like you need some help.
If I give you the correct answer mark me brainleist

First you would find the area of the square: 230*230= 52,900Next you would find the area of one on the triangles: 230*187=43,010 * 1/2= 21,505Then you would multiply the area of the one triangle by four: 21,505*4= 86,020Finally, you would add the area of the square to the combined area of the triangles: 86,020+ 52,900=138,920

Answer:

x(t) = - 5 + 6t and y(t) = 3 - 9t

Step-by-step explanation:

We have to identify the set of parametric equations over the interval 0 ≤ t ≤ 1 defines the line segment with initial point (-5,3) and terminal point (1,-6).

Now, put t = 0 in the sets of parametric equations in the options so that the x value is - 5 and the y-value is 3.

x(t) = - 5 + t and y(t) = 3 - 6t and

x(t) = - 5 + 6t and y(t) = 3 - 9t

Both of the above sets of equations satisfy this above conditions.

Now, put t = 1 in both the above sets of parametric equations and check where we get x = 1 and y = -6.

So, the only set, x(t) = - 5 + 6t and y(t) = 3 - 9t satisfies this condition.

Therefore, this is the answer. (Answer)
