Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
H = x, L = 1.5 x;
L + W + H = 6
x + 1.5 x + W = 6
W = 6 - 2.5 x
Dimensions of the camera in terms of x:
x, 1.5 x, 6 - 2.5 x.
V = L x W x H
V = x * 1.5 x * ( 6 - 2.5 x ) = 9 x² - 3.75 x³
V ` = 18 x - 11.25 x² ( V max is when V` = 0 )
18 x - 11.25 x² = 0
x ( 18 - 11.25 x ) = 0
11.25 x = 18
x = 18 : 11.25
x = 1.6
The dimensions are:
L = 2.4
W = 2.0
H = 1.6

Answer:
- Volume of the cube is 8 cubic feet.
Step-by-step explanation:
<u>Given that</u>:
- A cube has an edge length of 2 feet.
<u>To Find</u>:
- What is its volume, in cubic feet?
<u>We know that</u>:
- Volume of a cube = (Edge)³
<u>Finding the volume</u>:
⇒ Volume = (2)³
⇒ Volume = 2 × 2 × 2
⇒ Volume = 8
<u>Hence</u>,
- Its volume is 8 cubic feet.
