Answer:
use the slope formula!
Step-by-step explanation:
Rate of change is basically slope
you have to use the slope formula y2-y1/x2-x1
for example in the first question on the left 30-15 ÷ 5-2 = 5
would you like me to do the rest?
Ok so to find the sum of interior angles the formula is
s=180(n-2)
s is sum and n is the number of sides
so this is a quadrilateral cause it has 4 sides
because of that n=4
substitute
s=180(4-2)
now you can either distribute or do pemdas but its easier and more efficient to just do pemdas
s=180(2)
s=360 degrees
16:12 is the answer if you want you could do 16 baseballs over 12 golfballs
