16•16=256
A quarter is missing so 256/4=64
64•3=192 is the total square area.
When you find the area of a triangle you usually do (b•h)/2
Since this right here is equal triangles for both ways you can simply divide 192/2=96ft^2
72 hours because if you keep counting up by NInes 8 times you will hit 72

Answer:
(4,-4)
x=4
y= -4
Step-by-step explanation:
We know that y is equal to and so we can plug the y value in for x into the other equation
-2x+5(-x)= -28
Solve for x
-2x-5x= -28
-7x= -28
x=4
Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y
y= -(4)
y= -4
