Answer:
Step-by-step explanation:
P=(2,-3)
Q=(a,a²-2a-3)

Proof:
y'=(x²-2x-3)'=2x-2
y'(2)=2*2-2=2
Answer:
Area of triangle formula:
A = b*h/2
B is 18 and h is 13
B is base and h is height.
18 * 13 is 234.
We must divide by two because just multiplying the two numbers would result in an area of a square, divide by 2 for a triangle.
234/2 =
117 km²
Divide by 3 then subtract however many you have to
You will need 50 because 10 divided by 500 is 50 so you will need 50 markers.<span />
