Answer:
b=2a/h
Step-by-step explanation:
area=legnth times width
we notice this is a special case
(a+b)(a-b)=a^2-b^2
area=(a+3b)(a-3b)=a^2-9b^2
area=a^2-9b^2
To run the these figures to 3 decimal places
you need to count from the digit after the decimal point until you reach the 3rd number which is 2
so now the answer is 2470.283
This is because the decimal point lies between 2 and 7 and since 7 is great than 5 we add 1 to the 2 making it 3
Answer:
3x^2y\sqrt(y)
Step-by-step explanation:
(\sqrt() means square root
its the 2nd one
