Answer:
Step-by-step explanation:
The bases of a triangular prism are equilateral triangles, since they have equal sides: 5, 5, and 5
yes, since if all lateral faces are rectangles, rectangles are formed from 4 perpendicular segments, thus, if all edges of the lateral faces are perpendicular, then they are rectangles

Answer:
Width of rectangular piece = x = 8 inches
Step-by-step explanation:
Perimeter of rectangular piece = 62 inches
Let width of rectangular piece= x
and length of rectangular piece = x+15
We need to find width i.e value of x
The formula used for perimeter of rectangle is: 
Putting values in formula and finding Width:
After solving we get value of x = 8
So, Width of rectangular piece = x = 8 inches
<span>Reorder the terms:
-2.3(-1.2 + x) = -9.66
(-1.2 * -2.3 + x * -2.3) = -9.66
(2.76 + -2.3x) = -9.66
Solving
2.76 + -2.3x = -9.66
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2.76' to each side of the equation.
2.76 + -2.76 + -2.3x = -9.66 + -2.76
Combine like terms: 2.76 + -2.76 = 0.00
0.00 + -2.3x = -9.66 + -2.76
-2.3x = -9.66 + -2.76
Combine like terms: -9.66 + -2.76 = -12.42
-2.3x = -12.42
Divide each side by '-2.3'.
x = 5.4
Simplifying
x = 5.4</span>
