Y=6x+9. y=6x+2. Therefore y=6x+9=6x+2. 6x+9=6x+2. 6x-6x=2-9. 0=-7. This is not true. So this is- No solution
Answer:
Dimension of room = 18 foot x 18 foot
Step-by-step explanation:
Let the square room is of side a foot,
The cost of re-finishing the hardwood floors is $2.25 per square foot and the cost of purchasing and installing the new baseboards $14.5 per linear foot
Total cost is $1773.
Cost for re-finishing the hardwood floors = Area x 2.25
Area = a²
Cost for re-finishing the hardwood floors = 2.25 a²
Cost of purchasing and installing the new baseboards = Perimeter x 14.5
Perimeter = 4a
Cost of purchasing and installing the new baseboards = 4a x 14.5 = 58 a
Total cost = Cost for re-finishing the hardwood floors + Cost of purchasing and installing the new baseboards
1773 = 2.25 a² + 58a
2.25 a² + 58a - 1773 = 0
a = 18 or a = -43.77(not possible)
Dimension of room = 18 foot x 18 foot
Ax^2+bx+c=0 is the standard form, so we add 5 to both sides to get
1*x^2+(-10)x+21=0
Exact form is 8/7 , as a decimal its 1.142 and mixed number form its 1 1/7
