Answer:

The total area of the two rectangles is (5x^{2} +7x)\ units^{2}

Step-by-step explanation:

<em>Area of rectangle 1</em>

(x)(3x+1)=(3x^{2} +x)\ units^{2}

<em>Area of rectangle 2</em>

(2x)(x+3)=(2x^{2} +6x)\ units^{2}

therefore

The total area of the two rectangles is equal to

(3x^{2} +x)\ units^{2}+(2x^{2} +6x)\ units^{2}=(5x^{2} +7x)\ units^{2}

- A candy clerk has three times as many kilograms of chocolate creams as peanut clusters.
Lina20 [59]

The kilograms of peanut clusters that the clerk has will be 12 kilograms of peanut flusters.

Let the kilograms of peanut clusters = x

Let kilograms of chocolate creams = y = 3x

Therefore, from the information given, the equation to solve the question will be:

x + y = 48 kilograms

x + 3x = 48 kilograms

4x = 48 kilograms

x = 48 kilograms / 4

x = 12 kilograms

Therefore, the kilograms of peanut clusters that the clerk has will be 12 kilograms of peanut clusters.

In conclusion, the correct option is 12 kilograms.

Natasha2012 [34]

Answer:

45%

Step-by-step explanation:

225 of 500 can be written as:

225/500

To find percentage, we need to find an equivalent number with denominator 100. Multiply both numerator & denominator by 100

225/500 × 100/100

= (225 × 100/500) ×

1/100

=

45/100

Therefore, the answer is 45%

Hope this helps :)
