Find the number that must be added to each expression to form a perfect square trinomial. then write the trinomial as a binomial squared.

x^2+6x+

( )^2

i. or

ii.

Step-by-step explanation:

The given expression is

We add half the coefficient of x squared, which is

This simplifies to;

Or

Based on the question, you must write 3 inside

We add   to obtain

The expression as a binomial squared is

answer: .75 km

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
