Hello here is a solution :
The length of diagonal EK is sqrt(5^2 + 4^2) ≈ 6.403m
Hence perimeter = 2*(12 + 6.403) → 36.8 m (to the nearest tenth of a metre)
Check the picture below.
bear in mind that since we have a radical in the denominator, we'd
rationalize the denominator to take it off the denominator.
Answer:
B
Step-by-step explanation:
dont know how to explain but yeah
We calculate this by multiplying the number of cookies by the number of boxes:
28*14=(20+8)*14=280+80+32=360+32=392 (that's how I like to count it, there are also other methods)
so she has 392 cookies in common.
