Answer:
length = 24 meters
Step-by-step explanation:
1. l = 2w
2. P = 2l + 2w
P=72
3. 72 = 2l + 2w
4. Substitute w=l/2 to solve for l
72 = 2l + 2(l/2) ---> 72 = 3L - Divide by 3 on both sides
L= 24 meters

Answer:
- 84 small cubes
- 3 1/9 unit cubes
Step-by-step explanation:
A cube that is 1/3 ft on a side will fit 3 in a foot. In terms of the 1/3 ft small cube, the dimensions of the prism are ...
1 1/3 ft = 4 small cubes
1 ft = 3 small cubes
2 1/3 ft = 7 small cubes
Then the volume in terms of small cubes is ...
V = LWH = (4)(3)(7) = 84 small cubes
__
There are 3×3×3 = 27 small cubes in a 1-ft unit cube, so the prism volume in terms of unit cubes is ...
84/27 = 3 1/9 . . . unit cubes
__
<em>Additional comment</em>
The largest dimension of the prism is just over 2 ft, so the maximum number of unit (1 ft) cubes that will fit is 2. To fill the volume with 3 1/9 unit cubes, those would have to be cut and fit into the space.

Answer:
The answer to your question is x = 3
Step-by-step explanation:
Data
m∠2 = 10x + 10
exterior angle = 110°
x = ?
Process
1.- Find the measure of the angle supplementary to the angle 110°. It will be angle y.
180° = 110° + y
- Solve for y
y = 180 - 110
y = 70
2.- From the picture we conclude that the triangle is Isosceles because two of its sides measure the same.
In an Isosceles triangle two of its angles measure the same so,
180° = 70° + 70° + ∠2
- Solve for ∠2
∠2 = 180 - 70 - 70
∠2 = 40
3.- Find x
10x + 10 = 40
Solve for x
10x = 40 - 10
10x = 30
x = 30/10
x = 3
