Answer:
Part A: 115
Part B: 36000
Explanation:
Part A asks for the perimeter, which is adding, so add up the 15, 40, and 60, which will equal to 115.
Part B asks for the area, which is multiplying, so you multiply the numbers,
15 x 40 x 60 = <u>36000</u>
15 x 40 = 600
600 x 60 = 36000
You could try multiplying it a different way but get the same answer:
60 x 40 x 15 = <u>36000</u>
60 x 40 = 2400
2400 x 15 = 36000
I'm not sure if this is correct but I hope I helped
have a great day/night :))
Answer:
2.456 x 10^11
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
