Step-by-step explanation:
Hi there!
Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.
[(12*18)-(7*3)]/200
(215-21)/200
196/200
0.98
Answer:
-0.2+7k
Step-by-step explanation:
Rearrange the equation so that it is 1.8-2+7k
1.8-2=-0.2
You can't add 7k because it doesn't have a common variable
-0.2+7k
