A paper air plane looking polygon with sides of 5 5 and 8 what is the area
VARVARA [1.3K]
If it has 3 sides then it's a triangle. 
Using the formula A= \sqrt{s(s-a)(s-b)(s-c)} 
where s= \frac{a+b+c}{2}
and  a=5 b=5 c=8

∴s= \frac{5+5+8}{2} =9
  area= \sqrt{9(9-5)(9-5)(9-8)}
  area= \sqrt{144} = 12units^{2}

What is the difference written in scientific notation 1.3x10^6 - 6.8 x 10^5
Pavlova-9 [17]

One way to solve this is to revert to integers.

Do this by moving the decimal in 1.3 to the right 6 places (indicated by the positive power value) and then 6.8 move the decimal to the right 5 places (same reason)

Now you have 1,300,000 & 680000. Subtract to get 620,000.

Now convert your product to scientific notation again by moving your decimal to the left until you are left with 6.2 x ? The question mark will be 10 to the number of places you moved the decimal. 10^5

We have 6.2 x 10^5.

It is import to note that when the decimal must be moved to the right for values less than one, the power will be negative.
