Answer:
76,800
Step-by-step explanation:
Given the following :
Length = 20 kilometers
Width = 12 kilometers
Population density = 320 people per sq km
Population =?
Recall:
Area of rectangle = Length × width
Therefore,
Area of Rectangleville = 20 km × 12 km = 240km^2
Population is related to population density and Area by the formula ;
Population density = population ÷ Area
Therefore,
Population = population density × Area
Population = 320 × 240 = 76,800
Therefore, the population of Rectangleville is 76,800 people
4x^2 + 5x - 6 = (4x - 3) (x + 2)
You can do it by using the quadratic function to solve 4x^2 + 5x - 6 = 0; the result will be x = 3/4 and x = -2
Then you have to make (x- 3/4) = 0 and (x +2 ) = 0
When you develop x - 3/4 = 0 you get 4x -3 = 0, which means that 4x - 3 is a factor. The other factor is directly x + 2.
Answer: option b: (4x -3)(x + 2)

The question is incomplete as what is required is not stated.
Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa
Take for instance
Calculate the number of grapes when there are 20 strawberries
We have:
This becomes
Express as fraction
Make G the subject
<em>i.e. 50 grapes</em>
<em>Apply the same method given a certain number of grapes</em>
Answer:
20%
Step-by-step explanation:
To find the percent increase lets first find the increase.
36-30 = 6
Now divide the increase by the original amount
6/30 = 1/5 = 20%
