1. (3 + xz)(–3 + xz)
2. (y² – xy)(y² + xy)
3. (64y2 + x2)(–x2 + 64y2)
Explanation
The difference of 2 squares is in the form (a+b)(a-c).
(3 + xz)(–3 + xz) = (3 + xz)(xz -3)
= (xz + 3)(xz - 3)
= x²y²-3xy+3xy-9
=x²y² - 3²
(y² – xy)(y² + xy) = y⁴+xy³-xy³-x²y²
= y⁴ - x²y²
(64y2 + x2)(–x2 + 64y2)= (64y²+x²)(64y²-x²)
= 4096y⁴-64y²x²+64y²x²-x⁴
= 4096y⁴ - x⁴
There are 30.48 centimeters in 12 inches.
Step-by-step explanation:
Given,
1 inch = 2.54 centimeters
For x inches;
x inches = 2.54*x centimeters
x inches = 2.54x centimeters
Number of centimeters in 12 inches
We will put x=12
12 inches = 2.54(12) centimeters
12 inches = 30.48 centimeters
There are 30.48 centimeters in 12 inches.

In order to change a fraction into a decimal you must divide the numerator by the decimal so divide 1 by 8 and so as you go through the equation you get a decimal number because 8 cannot go into 1 of course.
Answer: 0.125 is the amount you ate in decimal form
<span> Nina + her 5 friends = 6 people
Then she has 9 apple to share with her and her friends.
Let’s calculate how many apple will each people get when they equally divide it
with each other:
=> 9 – 6 = 3
Thus already have 1 apple each, now, let’s divide the remaining 3 apples
=> 3 / 6 = .5
So they have half of apple each. Let’s add
=> 1 + .5 = 1.5
Each person will get 1.5 apple.
=> 1.5 * 6 = 9</span>
