Answer:
4cm
Step-by-step explanation:
Given data
L=(2x+3)
W=(x-1)
P=28cm
A= L*W
A= (2x+3)*(x-1)
open bracket
A= 2x^2-2x+3x-3
collect like terms
A= 2x^2+x-3
P= 2L+2W
P= 2*(2x+3)+2(x-1)
P= 4x+6+2x-2
collect like terms
P= 6x-4
but p= 28
28= 6x-4
28-4= 6x
24= 6x
x= 24/6
x= 4cm
Hence x= 4cm
Answer:
x < 2
Step-by-step explanation:

A. let the distance be d
so we have Δd/Δt=8.8min
Δd= 8.8Δt
d=∫8.8Δt-------(1)
b. d should be positive because the diver is ascending at a positive rate relative to depth
c. d=rt
t=d/r = 32.12/8.8 min
t= 3.65min
For this case we have that by definition, the volume of a cube is given by:

Where,
- <em>s: Side of the cube
</em>
We have that the cube side is given by:

Therefore, replacing values we have:

Answer:
One way to write the volume of the cube is:

Answer:
Negative infinity
Step-by-step explanation:
The line points down infinitely in the graph.
