Answer:
$ 117.36
Step-by-step explanation:
On the drawing, the rectangular room measures 3 inches by 2 inches, we can convert to feet (using a scale of Inch - 2 feet )
(3 inches ×2) by (2 inches ×2)
= 6 feet by 4 feet
The Area of the room can now be calculated as
Area=( 6 feet × 4 feet)
= 24 ft^2
how much will the new carpet cost?
we know that the carpet costs $4.89 per square foot, then the cost by the area of the room= (Area× $4.89 per square foot)
=24 ft^2 x $4.89
=$ 117.36
Hence, the new carpet cost is $ 117.36
Critical values are values where f'(x)=0 and the bounds of a function. Thus, let's solve for f'(x)!
f(x)=2x^3-3x^2+3x+8
f'(x)=6x^2-6x+3
Now let's set f'(x)=0
0=6x^2-6x+3
0=2x^2-2x+1
As it turns out, 2x^2-2x+1 isn't factorable!
This saves me some time because this means there are no critical numbers!
Answer:
144 units
Step-by-step explanation:
3x + 8 + 4x + 10 = 8x
7x + 18 = 8x
8x - 7x = 18
x = 18
8x is length of BC
8 × 18 is length of BC
144 units
