Answer:
Go through the explanation you should be able to solve them
Step-by-step explanation:
How do you know a difference of two square;
Let's consider the example below;
x^2 - 9 = ( x+ 3)( x-3); this is a difference of two square because 9 is a perfect square.
Let's consider another example,
2x^2 - 18
If we divide through by 2 we have:
2x^2/2 -18 /2 = x^2 - 9 ; which is a perfect square as shown above
Let's take another example;
x^6 - 64
The above expression is the same as;
(x^3)^2 -( 8)^2= (x^3 + 8) (x^3 -8); this is a difference of 2 square.
Let's take another example
a^5 - y^6 ; a^5 - (y ^3)^2
We cannot simplify a^5 as we did for y^6; hence the expression is not a perfect square
Lastly let's consider
a^4 - b^4 we can simplify it as (a^2)^2 - (b^2)^2 ; which is a perfect square because it evaluates to
(a^2 + b^2) ( a^2 - b^2)
Answer:
22,36,50,64,78,92
Step-by-step explanation:
The common difference is when you take one term and subtract the previous term from it.
For example, 36-22=14

Given:
Selling price of each pound of strawberries = $2.50
Selling price of each pound of raspberries = $3.75
Total quantity = 65 pounds
Total sales = $225
To find:
The number of pounds of strawberries sold, and the number of pounds of raspberries sold graphically.
Solution:
Let x be the number of pounds of strawberries and y be the number of pounds of raspberries sold.
According to the question,
Total quantity : 
...(i)
Total sales : 
...(ii)
Table of values for equation (i) is
x y
0 65
65 0
Table of values for equation (ii) is
x y
0 60
90 0
Plot these point on coordinate plane and connect them by straight lines as shown in the below graph.
From the graph it is clear that both lines intersect each other at (15,50). So,
Therefore, the number of pounds of strawberries sold is 15 and the number of pounds of raspberries sold is 50.
