Answer:
The actual distance is 56 km
Step-by-step explanation:
We can use ratio's to solve this problem
1 cm 8cm
---------- = -----------------
7 km x km
Using cross products
1 * x = 8 * 7
x = 56
x = 56 km
The first one is eight 4400-2400=2000 2000/250=8
A square has 4 equall side so if one side is 2x+3
then:
the perimeter is 2x+3 + 2x+3 + 2x+3 + 2x+3
Combine like terms and the answer is:
8x+12
