8. The figure below is a right triangle. If you change the distance from the light to the meteorology station to 400 meters rather than 300 meters, what is the new value for
x, to the nearest tenth of a meter?
22
300 m
light
033
012
meteorology
station
a. 990.0 m
b. 323.6 m
C. 431.4 m
d. 370.9 m

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
