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!
The formula for area of a square is s^2 so it would be 7; the perimeter would be 7+7+7+7= 28 and the area would be 7^2= 49
Answer:
4C2 * 6C2 * 5C2
Step-by-step explanation:
White balls = 4
Yellow balls = 6
Red balls = 5
In other to select a total of 6 balls, of which there must be 2 balls each of color white, yellow and red :
That means :
2 red balls from 5 red balls = 5C2
2 balls for 6 yellow balls = 6C2
2 balls from 4 white balls = 4C2
To obtain the number of possible combinations, take the product of the three combinations :
4C2 * 6C2 * 5C2

Answer:
(4,-3)
Step-by-step explanation:
If the line passes through a point, the coordinates of the point will verify the equation of the line.
So, let's see if each of the coordinates verifies the equation 3x - 2y = 6
A. (4,-3) means x=4 and y = -3
so 3x - 2y becomes 3(4) - 2(-3) = 12 - -6 = 12 + 6 = 18
B. (4/3, -1) means x = 4/3 and y = -1
so 3x - 2y becomes 3(4/3) - 2(-1) = 4 - -2 = 4 + 2 = 6
C. (-2,-6) means x= -2 and y = -6
so 3x - 2y becomes 3(-2) - 2(-6) = -6 - -12 = -6 + 12 = 6
Verified that the line passes by the last two points but not the first one.
