To find the area of a rectangle, we multiply the Base by the Height. In this case the: Base = AB and Height = BC
So to get the area, we multiply AB by BC. (and we know that <em>BC = 5x+5/x+3</em> <em>and BC = [3x+9/2x-4)</em>
So we would do:
x
Note: When multiplying fractions together, we multiply the numerator by the numerator, and the denominator by the denominator.
For example x
=
Answer: x
=
=
[<em>Note: </em><em>we are able to factorise some brackets to make the sum easier. For example we can factor out the 5 in (5x+5) to get: 5(x+1) ]</em>
Now lets simplify by multiplying the 5 and 3 together in the numerator:
=
If you notice, there is a (x+3) in numerator and the denominator. This means that we can cancel out the (x+3), to get the most simplified expression for the area:
=

Answer:
The Potato has a greater mass.
____________________________________________________
Step-by-step explanation:
In order to see which one of them has the greater mass, we're going to need to figure out how much one of them weigh.
Lets get the key information from the question:
5 potatoes = 1 kilograms (kg)
8 pears = 1,200 grams (g)
With the information above, we can solve the problem.
1 Kilogram = 1000 grams
With that information, we know that 5 potatoes would equal 1000 grams, now we would need to divide 1000 by 5 to get the grams for one potato in order to find the mass of it.
<u>1 Potato = 200 grams</u>
Now, we would need to divide 1,200 by 8 to find the mass of 1 pear.
<u>1 Pear = 150 grams</u>
With the information we have now, we would know that the Potato has the greater mass than the pear.
A potato has a greater mass.
