2x^2 is not a like term in the given expression (since the given like terms contain only 1 power of x)
Answer:
Step-by-step explanation:
Volume of the figure = Base area * height
Base area:
Base area = area of trpezium + area of triangle
<u />
<u>Trapezium:</u>
a, b area the length of parallel sides and h is the height of trapezium.
a = 8 m ; b = 5 m & h = 3 m


<u>Triangle:</u>
height = 4 m & base = 8 m


Base area = 19.5 + 16
= 35.5 m²
Volume of the figure = Base area * height
= 35.5 * 14
= 497 m³
From 9:00 am to 9:00pm, that's a total of 12 hours,
so 12 of the 20 hours are charged at a rate of 0.25 dollar per hour, and the other 8 hours (20-12=8) are charged at a rate of $0.06 per hour.
the answer is b.
it should be 0.06 though, not 0.6
