The area of a rectangle is obtained through the equation,
A = L x W
The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,
A = (L)(L-4) ; 96 = L(L - 4) ; L = 12 ft
The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,
P = 2 x (L + W)
Substituting the values of L and W
P = 2 x ( 12 ft + 8 ft) = 40 ft
Therefore, the perimeter of the yard is 40 ft.
Answer:
just multiply every number by 2 and it should work out.
Step-by-step explanation:
The copy machine makes 105 copies per minutes.
Step-by-step explanation:
Given,
Copies printed by photocopy machine = 735
Time taken by machine = 7 minutes
To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.
Copies printed in one minute = 
Copies printed in one minute = 105 copies
The copy machine makes 105 copies per minutes.

Answer:
t = 130s
Step-by-step explanation:





If the speed signal sent was actually less, meaning that it would take more time to signal arrives from Earth to Mars. The lower the speed, the higher the time.
In order to divide, you need to find the reciprocal of 4/15 and multiply it by 2/3. So, 2/3*15/4
The answer is 5/2
