A glass of orange juice contains 3.2 dL of juice. How many milliliters of orange juice are in the glass?
pogonyaev

Answer:

There are 320 milliliters of orange juice in the glass.

Step-by-step explanation:

Unit conversion problems can be solved by rules of three.

We have that each dL is worth 100 mL(milliliters).

How many milliliters of orange juice are in the glass?

How many ml are 3.2dL of juice?

1 dL - 100 mL

3.2 dL - x mL

x = 100*3.2

x = 320

There are 320 milliliters of orange juice in the glass.

If a rectangle has an area of 2x^2+7x+3 find the perimeter
nikdorinn [45]

Perimeter of a rectangle = 6x + 8

Solution:

Given area of a rectangle = 2x^2+7x+3

Let us first factor the given polynomial.

2x^2+7x+3=2x^2+x+6x+3

                    =(2x^2+x)+(6x+3)

Taking out common terms in the above expression

                    =x(2x+1)+3(2x+1)

Taking out common term 2x+1 in the above expression

                    =(2x+1)(x+3)

2x^2+7x+3=(2x+1)(x+3)

Area of a rectangle = l × b

Therefore, l=2x+1 and b=x+3

Perimeter of a rectangle = 2(l + b)

                                         =2[(2x+1)+(x+3)]

                                         =2(2x+1+x+3)

                                         =2(3x+4)

                                         =6x+8

The answer is same if you take <em>l</em> = x + 3 and <em>b</em> = 2x + 1.

Hence, perimeter of a rectangle = 6x + 8.
