Answer:
1 cm^2 = 100 mm^2
9 cm^2 = 900 mm^2
5.2 cm^2 = 520 mm^2
1 dm^2 = 100 cm^2
17 dm^2 = 1700 cm^2
4.3 dm^2 = 430 cm^2
1 m^2 = 10000 cm^2
7 m^2 = 70000 cm^2
2.5 m^2 = 25000 cm^2
1 km^2 = 1000000 m^2
50 km^2 = 50000000 m^2
8.5 km^2 = 8500000 m^2
Step-by-step explanation:
1 cm = 10 mm
1
= 10×10
= 100
9
= 9×100
= 900 
5.2
= 5.20×100
= 520 
1 dm = 10 cm
1
= 10×10
= 100 
17
= 17× 100
= 1700 
4.3
= 4.3 × 100
= 430 
1 m = 100 cm
1
= 100×100
= 10000 
7
= 7×10000
= 70000 
2.5
= 2.5×10000
= 25000 
1 km = 1000 m
1
= 1000×1000
= 1000000 
50
= 50×1000000
= 50000000 
8.5
= 8.5×1000000
= 8500000

6)worm out
7)sail through
Hope this helped :)
Answer:
1. multiply 32 on both sides to get rid of the fraction
which leaves you with
68≤1-u
2. You can add the U to one side and subtract 68 from the other side
which leaves you with
u≤-67
Answer: the coordinates of B' are (6, -13)
Justification:
1) Translating triangle ABC according to the rule (x,y) → (x + 2, y - 8) means that every single point of the triangle will be translated two units to the righ (x + 2) and 8 units downward (y - 8).
2) To find the coordinates of anay image you have to add up 2 to the x coordinate (x + 2) and subtract 8 from the y-coordinate (y - 8).
3) Peforming those simple operations to the coordinates of the point B (4, -5), you will obtain the point B':
* x' = x + 2 = 4 + 2 = 6
* y' = y - 8 = -5 - 8 = - 13
Answer: the coordinates of B' are (6, -13)
