Answer:

P = 16x - 30 units

Step-by-step explanation:

Let the length and width of the rectangle be (3x - 4) & (5x - 11)

$perimeter \: of \: rectangle \\ = 2(l + w) \\ = 2(3x - 4 + 5x - 11) \\ = 2(8x - 15) \\ = (16x - 30) \: units$

Answer:

P = 16x - 30

Step-by-step explanation:

P = 2L + 2W

P = 2(3x - 4) + 2(5x - 11)

P = 6x - 8 + 10x - 22

P = 16x - 30

hichkok12 [17]

Answer:

About 384.3 feet

Step-by-step explanation:

The formula for that is given by,

$S= \sqrt{30 \times d \times f \times n}$

Where,

S is the speed of the car

d is the distance of skid

f is the drag factor for the road surface

n is breaking efficiency as percentage

Putting the values we get,

$S^2= 30 \times d \times f \times n$

$d= \frac{S^2}{30 \times f \times n}$

$d = \frac{70^2}{30 \times 0.50 \times 0.85} = 384.3$ feet

So the length of skid marks would be 384.3 feet.
