Answer:
21
Step-by-step explanation:
Hi there!
We are given the expression x(y-z), and we want to evaluate it if x=3, y=9, and z=2
As we're given the values of the variables, we can substitute those values into the expression to find out what the value of the expression is.
So substitute 3 as x, 9 as y, and 2 as z in the expression above
x(y-z)
3(9-2)
Now we must follow the order of operations; start by subtracting 2 from 9 (do the stuff inside the parentheses first)
3(7)
Now multiply 3 and 7 together
<u>21</u>
Hope this helps!

Idrk how to do this
I just answered a similar question here:

In general, a positive constant moves the function upwards and a negative one moves it downwards.
To shift a function left, you add units to the independent variable. To shift it right, you subtract a constant from "x".
So, the answer in your problem is:
<span>The graph is shifted left 6 units.</span>
If segments AB and CD are congruent, then they have equal lengths:
5x-2=2x+7.
Solve this equation.
1. Separate terms with x and without x in different sides:
5x-2x=7+2,
3x=9.
2. Divide by 3:
x=3.
Then CD=2x+7=2·3+7=6+7=13.
Answer: correct choice is B.
The data value 110 would be considered an outlier, all of the numbers are within the range 20 to 40.
