To find the answer to that, you have to see how many numbers are between 13 and 31. There are 18 numbers between 13 and 31. Divide 18 by 2 and you will get the number halfway. 9 is halfway between 13 and 31. So, add 9 to 13 and you get 22.
The answer is 22.

Answer:
3
Step-by-step explanation:
x=5 and y=2, so we just have to plug them into the equation.
(2+5)-2(2)
7-4
7-4=3
Answer:

Step-by-step explanation:
The missing details are:

--- Midpoint of ST
Required
Determine the coordinates of S
To do this, we apply the mid-point formula:

Where


The equation becomes:



Multiply through by 2


By comparison:





Hence, the coordinates of S is:

What is the surface area of a rectangular prism?
formula.
A = 2(wl + hl + hw)
now we plug the numbers in our values (variables)
A = 2( 4(8) + 5(8) + 5(4) ) simplify the values inside parenthesis
A = 2( 32 + 40 + 20 ) add values
A = 2(92) multiply 92 and 2
A = 184 answer
I hope this helps!
