Answer quick ? simplify the expression

1/3

Step-by-step explanation:

So because of BODMAS / PEDMAS /  whatever you call it, you do the brackets first.

(7-2) = 5

5 squared is 25

So 25 is on the top.

Then we do the bottom one. We do square/cubed/quadrupled numbers first, so 3 to the power of 4 is 81.

4+81=85

85-10=75

So the bottom number is 75.

25 / 75 is the fractions so simplified that would be 1/3

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,
