A.
V=LWH
10,800= (3x)(2x+1)(12) here I would divide out the 12, then distribute the 3x
900= 6x^2 +3x
6x^2 + 3x -900= 0 now use the quadratic formula to find x
x= 12
B. now plug in the x into each given dimension
L= 3x= 3(12)= 36
W=(2x+1)= 2(12)+1= 25
Answer:
It is just 65.
Step-by-step explanation:
<span>... because there are more molecules to heat in 100 liters than in 10 liters.
_____
This assumes energy is supplied to the water at a constant rate, and that the various volumes of water are liquid at the same starting temperature and pressure.</span>
V(4,-2)
In the vertex form, the h value is the x and the k value is the y.
So if the vertex (4,-2) is also (h,k)
You can just simply replace the h and k in (x-h)^2+k.
Which gives us...
f(x)=(x-4)^2-2.
Answer:
W = 14, L = 18
Step-by-step explanation:
If L = length and W = width, then:
252 = LW
L = W + 4
Substituting:
252 = (W + 4) W
252 = W² + 4W
0 = W² + 4W − 252
0 = (W + 18) (W − 14)
W = -18 or 14
Since W > 0, W = 14. Which means L = 18.
