Answer:
Perimeter: 310 units
Step-by-step explanation:
If x=4 and y=5, then the measure of the lengths would be..
8y+19= 8(5)+19= 59
8x+64= 8(4)+64= 96
13y-6= 13(5)-6= 59
16x+32= 16(4)+32= 96
To check if all these measurements are congruent, we can see if they match up with the measure of their parallel line, which they do in this case because 59=59
96=96
To find the perimeter of any shape, we add all the side lengths together
59+59+96+96= 310

Answer:
y = 2*x^2 - 2*x - 24
Step-by-step explanation:
If we have a quadratic function with roots a and b, we can write the equation for that function as:
y = f(x) = A*(x - a)*(x - b)
Where A is the leading coefficient.
In this case, we know that the roots are: 4 and -3
Then the function will be something like:
f(x) = A*(x - 4)*(x - (-3) )
f(x) = A*(x - 4)*(x + 3)
Now we need to determine the value of A.
We also know that the graph of the function passes through the point (3, -12)
This means that:
f(3) = -12
Then:
-12 = A*(3 - 4)*(3 + 3)
-12 = A*(-1)*(6)
-12 = A*(-6)
-12/-6 = A
2 = A
Then the equation is:
y = f(x) = 2*(x - 4)*(x + 3)
Now we need to write this in standard form, so we just need to expand the equation:
y = f(x) = 2*(x^2 + x*3 - x*4 - 4*3)
y = f(x) = 2*(x^2 - x - 12)
y = f(x) = 2*x^2 - 2*x - 24
Then the relation is:
y = 2*x^2 - 2*x - 24
