Answer:
h = 
Step-by-step explanation:
Formula for the area of a trapezoid is,
Area (A) = 
Here b and c are the bases and 'h' is the height of the trapezoid.
2A = ![2[\frac{1}{2}(b+c)h]](https://tex.z-dn.net/?f=2%5B%5Cfrac%7B1%7D%7B2%7D%28b%2Bc%29h%5D)
2A = (b + c)h
Therefore, formula for the height of the trapezoid will be,
h =

x=5 y=8
Step-by-step explanation:
here's your answer. Please mark as brainliest
<span>C = 45 + 18 + 27 - 21 - 93
C = -24
Let's use the variable C to represent the change in the balance in Cody's checking account. The easiest way to make the expression is to simply apply the additions and subtractions directly. So let's start with C
C
"Cody made deposits of $45, $18, and $27 into his checking account."
C = 45 + 18 + 27
"He then wrote checks for $21 and $93."
C = 45 + 18 + 27 - 21 - 93
So the expression to represent the change to Cody's checking account is
C = 45 + 18 + 27 - 21 - 93
Now to simplify it. All you need to do is combine terms together. How far you go is up to you. So let's do it.
C = 45 + 18 + 27 - 21 - 93
I'll add together all the deposits.
C = (45 + 18 + 27) - 21 - 93
C = 90 - 21 - 93
And I'll combine the checks.
C = 90 - 114
So now you can tell at a glance that Cody deposited $90 and wrote checks for $114. But we can make it simpler and combine those as well. So
C = -24
And this tells you that Cody's checking account balance is now $24 lower than it was before he started making deposits and writing checks.</span>
