Amap is draw so that every 1 inch on the map represents 50 actual miles. the table below can be used to record the actual distances between towns on the map

200

Step-by-step explanation:

Since we know that every inch on the map is equal to 50 miles, and the table doesnt give us any information other than that you can just add

50=1 inch

100=2 inches

150 =3 inches

200= 4 inches

so 4 inches on the map is 200 miles..

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
