on the scale of a map 4 cm represent 20 km if the distance between two points is 10 cm what is the actual distance between this points​

50 km

Step-by-step explanation:

Given

-- Scale ratio

Required

Actual representation of 10cm

Let the actual measurement be x.

So, we have:

Equate both value s of r

Express as fraction

Multiply by 10cm

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
