The length of the envelope is 6.3 inches
Step-by-step explanation:
Width of the envelope = 3 inches
Diagonal of the envelope = 7 inches
To find:
The length of the envelope.
Let the length of the envelope be 'l'
We can use pythogoras theorem to calculate the length.
l = √(49-9)
l = √(40)
l = 6.3 inches
The length of the envelope is 6.3 inches
Answer:
No Solution
Step-by-step explanation:
8x+2y=13 4x+y=11 Subtract 4x on both sides to isolate y
y=-4x+11 <---- Substitute this equation into the
equation 8x+2y=13
8x+2(-4x+11)=13
8x-8x+22=13
22=13 (not true)
No Solution
Answer:
The answer is 49
Step-by-step explanation:
the square = 10×4= 40
The triangle = 6×3= 18 >> 18÷2 = 9ft
40+9= 49ft
