x=1/4
Step-by-step explanation:
perimeter of a rectangle
2(L+w)
-2x-6(4x+4)
open the bracket
-2x(4x+4)-6(4x+4)
-8x^2-8x-24x-24
-8x^2-32x-24
2(-8x^2-32x-24)
-16x^2-64x-48
coefficient of x is 64
16=64x
Answer:
x = 5
The opposite sides of a rectangle are equal , then perimeter
2(- 2x - 6) + 2(4x + 4) = 16 ← distribute parenthesis and simplify left side
- 4x - 12 + 8x + 8 = 16
4x - 4 = 16 ( add 4 to both sides )
4x = 20 ( divide both sides by 4 )

d + c liters
B
Because it starts from the smallest negative prefix to largest
80n = 68*100
80n = 6800
n = 6800/80
n = 85
