We are planning an experiment to see whether the new pet food is safe for dogs to eat. We will feed some animals the new food and others a food known to be safe, comparing their health after a period of time. In this experiment, how will you implement the principles of control, randomization, and replication?

Consider this expression and the steps to evaluate it. 4^5(−2)^9/4^8(−2)^3 1. apply the quotient of powers:      (−2)^a/4^b 2. evaluate powers:           c/d select the value of each variable. a = _ b = _ c = _ d = _

A)a square brown tarp has a square green patch green in the corner the side length of the tarp is (x + 8) and the side length of the patch is x what is the area of the brown part of the tarpb)a square red placemat has a gold square in the corner the side length of the gold square is (x - 2) inches with the width of the red region is 4 in what is the area of the red part of the placemat

Solve for the equation x. 2x + 22 = 4(x + 3)
