Answer:
The answer to this question is: 12.96 ft ≈ 13 ft
Step-by-step explanation:
Data
Area 168 ft²
Length = ?
Volumen = 0.42 gallons
But we do not need the volume of paint because we know that the wall is squared-shape.
Only we need to know the formula to obtain the area of an square.
Formula area = length²
So 168 = length²
Finally √168 = length
length = 12.96 ≈ 13 ft
You can set up an equation to figure this out.
-152+x=12
Add 152 to both sides and you get:
x=164
Step-by-step explanation:
Hey there!
Given;
-6(2x-9) + (7-6x) = 0
Simplify it.
-12x + 54 + 7 - 6x = 0
-18x +61 = 0
Therefore, answer is option B.
