The length of a rectangle is 6 centimeters greater than the width. The area of the
mylen [45]

Answer:

Step-by-step explanation:

Width = w

Length = w + 6

Area = 112 sq. cm

length * width = 112

(w +6 ) *w = 112

w²  +6w -112 = 0

Sum = 6

Product = -112

Factors = 14 , -8    {14 - 8 = 6 , (-8)*14 = -112}

w² +  14w - 8w -112 = 0

w(w + 14) - 8(w + 14)=0

(w +14)(w -8) = 0   {Ignore w + 18 as measurement won't be negative}

w - 8 = 0

w = 8 ft

Length = 8 + 6 = 14 ft

A jewelry box is designed such that its length is twice its width and its depth is 2 inches less than its width the volume of th
Sedaia [141]

Answer:

Volume = 2x^{3}-4x^{2}

Step-by-step explanation:

Let x be the width of the jewellery box

Given:

Length of the box is twice its width

Length of the box = 2\times width

Length of the box = 2\times x= 2x

depth of the box is equal to 2 inches less than its width.

depth of the box = width-2

depth of the box = x-2

The volume of the box is 64 inches.

Solution:

We know that the formula of the volume is.

Volume = length\times width\times depth

Now we substitute all known value in above.

Volume = 2x\times x\times (x-2)

Volume = 2x^{2}(x-2)

Volume = 2x^{3}-4x^{2}

Therefore, the equation of the volume of the box is.

Volume = 2x^{3}-4x^{2}
