Answer:

x=1 and x=-5

Step-by-step explanation:

To finally get the answer we will set everything equal to 0 so we will get

-2 = 0

This is an extraneous solution aka an answer that just doesn't make sense so we disregard the answer. This is really only useful to do if there is an x on the outside of the parenthesis.

x-1 = 0

add 1 on both sides

x-1

x+5=0

subtract 5 on both sides

x=-5

The scale of a map is 1:4 000 000. Hint: 1:4 000 000 means that 1cm on the map = 4 000 000 on the ground. The distance between L

Answer:

325 km

Step-by-step explanation:

Given the scale :

1 : 4 ,000, 000

1cm measure in map = 4000000 on the ground

From the map :

Distance between Leeds and London = 8.125 cm

The actual distance on ground can be calculated thus :

1cm = 4,000,000

8.125cm = x

Cross multiply

x = 32500000 cm

Converting to kilometers :

1 km = 100,000 cm

x = 32500000

Cross multiply

100,000x = 32500000

x = 32500000 / 100000

x = 325

Hence, actual distance between Leeds and London is 325 km
