Answer:
And find it all urself
Step-by-step explanation:
There are two triangles (top and bottom) and 3 rectangles.
the area of the three rectangles is 10*12+10*9+10*7=280
Area of each triangle: 1/2 of 12*5=30
area of two triangles: 30+30=60
Total surface area: 280+60=340 m²
60 street houses can use those digits.
For this case we have the following expression:

By definition of multiplication of powers of the same base, we have to put the same base and add the exponents, that is:

So:

Answer:

Draw a horizontal line with vertical tick marks. Draw one in the middle of the horizontal line for 0, then draw 4 vertical ticks for every whole integer, this will split the number into quarters.
Draw enough to have up to positive 4 on the right side of 0 and -2 on the left side of 0 and label it with the given numbers.
