8. At time t hours, there are 16^-2t bacteria of type A and 64^3t-1 bacteria of type B organisms in a sample. When will the number of each type of bacteria be equal?

umm im not really sure because i never had to do this

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

3xy cannot be combined with the others

2x, -5x and x are like terms
