Answer:
A
Step-by-step explanation:
Given
- 2 +
= 6 ( isolate the radical by adding 2 to both sides )
= 8 ( square both sides )
3x - 2 = 8² = 64 ( add 2 to both sides )
3x = 66 ( divide both sides by 3 )
x = 22 → A
Dimensions of the hallway mural:
L = x + 6, W = x - 2.
An expression is:
A ( hallway mural ) = ( x + 6 ) · ( x - 2 )
If x = 8 ft ( length of each side of the classroom ):
A ( h. m . ) = ( 8 + 6 ) · ( 8 - 2 ) =
= 14 · 6 = 84 ft²
The area of the hallway mural is 84 ft².
