Let x represent the width of the rectangle.
We know 2x=length
Perimeter of a rectangle is 2(length)+2(width)
So we can make an equation for the perimeter of this particular rectangle.
2(2x)+2(x)=60
4x+2x=60
6x=60
x=10.
Since the width is equal to x, we know that the width of this rectangle is 10 m.
And, the length is twice of the width.
10*2=20
Therefore, the length of the rectangle is 20 meters.
Answer:
C) x≥4 and x ≤ -4
Step-by-step explanation:
| 8x | ≥ 32
To remove the absolute values, we get two equations, one positive and one negative
8x ≥ 32 and 8x ≤ -32
Divide each side by 8
8x/8 ≥ 32/8 and 8x/8 ≤ -32/8
x ≥ 4 and x ≤ -4
