Answer: Width = 3 and Length = 14
Step-by-step explanation:
Length = 2W + 8
Width = W
Perimeter= 2(width) + 2(length)
34 = 2W + 2(2W +8)
Distribute
34 = 2W + 4W + 16
Combine like terms
34 = 6W + 16
Solve for W
34- 16 = 6W
18 = 6W
W = 3
Substitute 3 in for W in Length equation.
L = 2(3) + 8 = 14
Answer:
2(3x-2(3x+2)
Step-by-step explanation:
1) 18x^2-8
2) 2(9x^2-4)
3) 2(3x-2)(3x+2)
Answer:
In triangle EFG,
EG = 4.8 units
Since angle FDE = angle FED,
EF = FD = 3.5 units [sides opposite to equal angles]
FG = DE = 3 units [Given]
s = (a+b+c)/2
= (EG+EF+GF)/2
= (4.8+3.5+3)/2
= 11.3/2
now using Heron's formula,
area of EFG =
Step-by-step explanation:
The range of communication is about 55 meters.
