If you are finding the sample space see if it is biased or not. and if it population then find the experimental or theoretical.
Answer is A
144 + 12y + y^2
if perfect square should be
144 + 24y + y^2
Answer:
567 square yards
Step-by-step explanation:
The Area for 1 Triangular playground = 1/2 × Base × Height
The base of the triangle is 18 yards. The height of the triangle is 21 yards.
Hence:
= 1/2 × 18 yards × 21 yards
= 189 square yards
The area of the Triangular 3 playground is given as:
= 3 × 189 square yards
= 567 square yards
Hi, seems like the answer is f(x) = x - 4
Edit: this was my original answer, but I was apparently completely out of my mind when I wrote it. The correct answer is f(x) = -4x + 50, as I stated below. I'm very sorry for any trouble I caused
