The expression you have is already in its simplest form. However, there is another way to write it.
m - n/4
This expression is the same as the original, apart from the fact that we wrote the division as a fraction.
Answer:
16 inches
Step-by-step explanation:
Given,
Perimeter = 72 inches
Breadth = 20 inches
Perimeter = 2 ( L+B )
72 = 2 ( L+20)
72= 2L + 40
72-40=2L
32/2=L
L=16 inches
therefore , lenght of the tile is 16 inches

Answer:
690 sq in
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base
The triangular base has an area of
B = 1/2bh 1/2(5)(12) = 30
LA = ph where p is the perimeter of the base and h is the height of the prism
LA = (12 + 5 + 13)(21) = 30(21) = 630
SA = 630 + 2(30) = 630 + 60 = 690 sq in
