Answer:
The expression which will result in difference of two squares is:
(–7x + 4)·(–7x – 4)
Step-by-step explanation:
We know that the formula of the type:
(a-b)(a+b)=a²-b²
i.e. it is a difference of two square quantities. (a^2 and b^2)
since,
a= -7x , b=4
(-7x+4)(-7x-4)= (-7x)² - (4)²
=(7x)² - 4²
So the expression is a difference of two square quantities:
(7x)² and (4)²
Hence the answer is (–7x + 4)·(–7x – 4)....
Answer:
27
Step-by-step explanation:
Let's call boys and girls 3x and x respectively. Since 3x + x = 36, x = 9. Boys = 3x = 3 * 9 = 27.

Answer: 3/4
Step-by-step explanation: At the top you can see it is dividing by two so whatever you do to the numerator has to be done to the denominator. 6÷2=3 and 8÷2=4.
Hope this helps!
