Answer:
A = <u>40</u> 
Step-by-step explanation:
The equation for finding the area of a trapezoid is
.
In this equation, a=4, b=6, h=8.
.
4+6=10
10/2=5
5x8=40
Hope this helps!
Plug in your Y value into the bottom equation like so:
4x + 3x-3=11, combine like terms
7x-3=11 solve for x
7x= 14
x=2
Plug in x value into first equation
y = 3(2) -3
y= 6-3, y = 3
answer: (2,3)
Mean: so basically you add up all the numbers (5+12+1+5+7=30) and divide the sum (30) with how many numbers there are (5) so 30/5=6
mode: mode is numbers repeated, since there are two 5's it is the mode (you may also have multiple modes)
X/2-20=22
440 is your answer
