1.) Max is driving 42 miles per hour. A dog dog runs into the street and max reacts in about three quarters of a second. What is

Nostrana [21]

Answer: $14.07\ m$

Step-by-step explanation:

Given

Max is driving at a speed of $42\ mph$

It took him three-quarters of a second i.e. $0.75\ s$

Speed in meter per second is $18.77\ m/s$

Distance is given by

$d=v\times t$

Reaction distance is

$d=18.77\times 0.75=14.07\ m$

A sidewalk has an area that can be represented bt the expression (8x+24) feet. List 3 possible lenghts and widths of the sidewal

Eddi Din [679]

Answer:

Length = 8 feet and Width = (x+3) feet

Length = 4 feet and Width = (2x+6) feet

Length = 2 feet and Width = (4x+12) feet

Step-by-step explanation:

We are given that,

Area of the rectangular sidewalk = (8x+24) feet²

Since, area of a rectangle = Length × Width

It is required to find three possible lengths and widths.

As, we can factor the given area in the following ways,

1. Area = (8x+24) = 8 × (x+3)

2. Area = (8x+24) = 4 × (2x+6)

3. Area = (8x+24) = 2 × (4x+12)

Thus, the three possible lengths and widths are given by,

1. Length = 8 feet and Width = (x+3) feet.

2. Length = 4 feet and Width = (2x+6) feet.

3. Length = 2 feet and Width = (4x+12) feet.
