Answer:
4−12x
Step-by-step explanation:
It can go 78.75 or 78 3/4 meters in one second. Since it gave you 2/3, you divide 52.5 by 2, and then multiply it by 3.
Answer:
The area of trapezoid is 20 square centimeters
Step-by-step explanation:
Let
x -----> the length of rectangle
y ----> the height of rectangle
h ----> height of trapezoid
Applying the Trapezoid Mid-segment Theorem we have that
----> equation A
---->
----> equation B
Remember that
The area of rectangle is equal to

The area of trapezoid is equal to
-----> equation C
substitute equation A and equation B in equation C

The area of trapezoid is two times the area of rectangle
therefore
The area of trapezoid is 20 square centimeters
i think that it is the third one
