Hello there!
The formula to find the area of a trapezoid is:
A =
Since we have everything, we just plug them in :)
A =
A = (3x+3x+4)/2 (x) + (3x+3x+4)/2 (2)
A= <span><span><span><span>3x^2</span>+<span>2x</span></span>+<span>6x</span></span>+<span>4
A = </span></span><span>3x^2+8x+4
The correct answer is option A
I hope I helped!

Answer:
-1
Step-by-step explanation:
Given: Mean= 25 minutes.
Standard deviation= 2 minutes
x= 23 minutes.
Lets find the z-score for the number of sandwiches delivered in less than 23 mins.
Formula: Z-score=
Z-score=
⇒ Z-score=
∴ Z-score will be -1
Hence, -1 is the z-score for the number of sandwiches delivered in less than 23 minutes.
