The answer is -25
3-8=-5
-5*5=-25
There are four rectangles and 2 squares.
Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________
Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2
TOTAL: 392+392 = 784 cm^2
Wow I should have realized the the 4 rectangles are the area as the two squares.
Good luck to you!
If you have any other math questions, I can try my best to answer them. Just send me a comment or whatever works.
For this problem, given that this is a recursive series. The next term in the sequence is:
16
The reason is because the distance between two consecutive terms is always equal to two
1. Total area of water = 352,000,000 + 9 * 10^6
= 352,000,000 + 9,000,000 = 361,000,000 = 3.61 * 10^8
Fraction of the surface covered by water = 3.61 * 10^8 / 5.1 * 10^8
= 3.61 / 5.1 = 0.707843 = 70.78 % to nearest hundredth of a percent.
Answer:
there are multiple 0's in the same area, and multiple 2's.
