(22) If x² = 225, then x =
(24) If x= 343, then x =

Hi there!

Your answers are:

22) x= 15

24) **REFER BELOW**

Step-by-step explanation:

22)

x^2 = 225

Find the square root of both sides!

√x^2 = x

√225 = 15

x= 15

24)

X= 343

If unaltered x is equal to 343, then x itself is equal to 343

If you accidentally made a typo and meant to say x^2 = 343;

x^2 = 343

find the square root of both sides!

√x^2 = x

√ 343 = 7√7 or roughly 18.52

Hope this helps!

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,
