Answer: 2a^5+5b
Step-by-step explanation:
This is actually pretty simple
The exponent with the same power can be subtracted so
4a^5-2a^5 is 2a^5 like 4x-2x which is equal to 2x
4b+b is equal to 5b
2a^5+5b is your answer
11 / 634
Decimal form: 0.017350158...(there are probably more digits, but these are all that fit on my calculator screen)
Fraction form: 11/634
634 / 11
I have attached an image of this problem completely worked out.
Look at the picture.
The area of the hexagon is equal six times the area of the <span>equilateral triangle.
The formula of the </span><span>equilateral triangle with the leg
a:

Therefore the formula of the area of the hexagon with a side lenght
a is:

We have
a = 12cm. Substitute:
