The length of a rectangle is twice its width, while the

hoa [83]

Answer: Length = 12 units

Width = 6 units

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Since the length of a rectangle is twice its width, thus means that the length will be: = 2x

Perimeter of a rectangle = 2(l + w)

where,

L = length

W = width

Therefore,

Perimeter = 2(l + b)

36 = 2(2x + x)

36 = 2(3x)

36 = 6x

x = 36/6

x = 6

Width = 6 units

Length = 2 × Width = 2 × 6 = 12 units

The daily profit, P, of a local bakery can be calculated using the formula P=m-(250+4h) when employees work a total of h hours a

qwelly [4]

Answer:

$m=665+4h$

Step-by-step explanation:

Profits of the local bakery is given by

$P=m-(250+4h)$

where

m = Amount of money to be received

P = Profit

h = Number of hours worked

Now P = $415

So,

$P+(250+4h)=m\\\Rightarrow m=P+250+4h\\\Rightarrow m=415+250+4h\\\Rightarrow m=665+4h$

The equation to calculate the amount of money, m, the bakery should receive if the desired profit is $415 is $m=665+4h$ .
