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

The width of rectangle is 10 cm.
Step-by-step explanation:
Perimeter of rectangle = 60 centimeters
Let,
w be the width of rectangle.
The length of a rectangle is twice the width.
length of rectangle = 2w
We know that;
Perimeter = P = 2(Length+Width)
P = 2(2w+w)
Solving the Equation;
Dividing both sides by 6;
The width of rectangle is 10 cm.

Answer:
x = -1
Step-by-step explanation:
<h2>
first divide 8 by 2, to get 3x-4 =x-6. then, add four on both sides to get 3x = x-6 + 4. to x's and number on different sides, you are now going to subtract 1x from both sides to get 2x = -6 + 4. solve to get 2x = -2. lastly, divide both sides by 2 do get <u>x = -1</u>
