Three of the potions the Plaid Wizard often works with are Star Sand, Diamond Dirt, and Liquid Light. If the formula that represents the amount of Star Sand in a creature's body is given by S(t)=16⋅(1/7)^t, what is the half-life of Star Sand? Enter your answer as a number rounded to two decimal places, like this: 4.25

4 + 5 7/9= 9 7/9

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
