Step-by-step explanation:


Can I have the brainliest please?
I don't know if this helps/if you have learned this yet but it is a characteristic of a parallelogram that opposite sides are congruent. If this does not help please respond and I will do my best to help! I don't know if I 100% understand what you are asking!
3/8 = 0,375
5/12 = 0,416
5/12 is bigger
4400 - 3600 = 800
Decrease = 800 Calories
Original value was 4400 Calories.
Now,

After Rounding off,
Decrease percentage will be 18 %
Use Pythagoras's theorem.

Now, minus 12 from 15:
15 - 12 = 3,
which you need to square.
So the length of a = 9cm.
You can also do:

Which gets 9.
Hope this helps.
