a)
Dimensions: 7.5m x 4.5m
Cost , x= $14.17/m^2.
The area of the rectangular room can be calculated as,

Now, the cost of carpeting the rectangular room is,

Therefore, the cost of carpeting the room with dimensions 7.5m x 4.5m is $478.24.
b)
Dimensions: 17 yd. x 12 yd.
Cost, x= $25/yd^2.
The area of the rectangular room can be calculated as,

Now, the cost of carpeting the rectangular room is,

Therefore, the cost of carpeting the room with dimensions 17 yd. x 12 yd is $5100.
Answer:
(x-2 )= 18
(4xt1) = 81
i got it because x=20 mark branliest if you can thanks

Complete the square on the left side:

Then the equation becomes

Both 14 + √186 and 14 - √186 are positive numbers, so we can take the logarithm (base 3) of both sides without issue:

Then in increasing order, the solutions are
<em>c</em> = log₃(14 - √186), <em>c</em> = log₃(14 + √186)
