To find the area of the trapezoid you add the two bases then multiply by the base and divide by 2.
B1+b2= 24+16=40
40*h=40*12=480
480/2=240
D. 240 square feet.
Y=3x+19
You add 3x to each side. Because your trying to get y by its self like y=mx+b.
Answer:
255.5 miles
Step-by-step explanation:
146 miles - 2 hours
