Answer:
32
Step-by-step explanation:
The perimeter is equal to sum of side lengths
4x + z + 3 + 5z - 3 = 80 add like terms
10z = 80 divide both sides by 10
z = 8 PR is 4z so 8*4 = 32

Answer:
Step-by-step explanation A line of best fit is often useful to attempt to represent data with the equation of a straight line in order to predict values that may not be displayed on the plot.n:
To find the x value of the vertex we do:
x =

if your quadratic function is in the form ax² + bx + c = y
x =

x =

Now we plug this x into the equation and solve for y.
y =

y =

y =

y =

y =

y =

Your vertex (if my math is correct) is at
