Let us assume the width of the rectangle = x meters
Then
Length of the rectangle = 2x + 2
Perimeter of the rectangle = 16 meters
Then
Perimeter = 2 (Length + width)
16 = 2(2x + 2 + x)
16 = 2(3x + 2)
16 = 6x + 4
6x = 16 - 4
6x = 12
x = 2
Then
Length of the side of the rectangle = 2x + 2
= (2 * 2) + 2
= 6
I hope that the procedure is clear enough for you to understand and this is the answer that you were looking for.
Answer:
9 gram/cm³
Step-by-step explanation:
Volume of a square (L³) = 2³ = 8cm³
Volume of a square (L³) = 2³ = 8cm³
But Density = mass/volume
But Density = Mass/Volume
Density = 72grams/8cm³
Density = 9grams/cm³
Answer:
Infinitely Many Solutions.
Step-by-step explanation:
x+2y=0
6y=-3x
y=-3/6x
y=-1/2x
x+2(-1/2x)=0
x-2/2x=0
x-x=0
0=0
infinitely many solutions
