Answer:
490.0...
Step-by-step explanation:
4.9 x 10^2
(squared)
4.9 x 10 x 10
the easiest way to do this is to move the decimal 2 places to the right, as
10 x 10 = 100
4.9 x 100 = 490.0...
Each term differs by -68 and the first term is -68, we have:

As an expession it's just -68n.
1) 0.4
2)0.875
i dont know the 3 and 4 one
Answer:
158 m²
Step-by-step explanation:
I made this into 3 rectangles.
Figure 1:
9•8=72
The 9 is from the 13 m side, but I've taken 4 m off from the overlapping square.
Figure 2:
6•7=42
The 7 is from the 10 m side, but I've taken 4m off from the overlapping square again.
Remaining Area:
If you extend the lines into figures 1 and 2 from the top left corner and bottom right corner vertically, you will get a rectangle that is (11 m) x (4 m). This is not yet accounted for.
11•4=44
Add together: 72 + 42 + 44 = <u>158</u>
*Note: You could also find the area of the squares a much easier way by subtracting the overlapping part after finding the area of both figures , but this is how I did it*
