Hello,
1)
x= the width
2x=the length
x-3= the height
V=x*2x*(x-3)=2x^3-6x²
2)
16-8=8
24-16=8
32-28=8
difference=8
answer D
3)
a) if you put the squares side by side horizontaly you will need 37*34=1258 squares (for a perfect job)
b) or 109*103/9≈1248 squares (cutting squares)
<h2>
Answer:</h2>
The type of reasoning which starts with a given set of rules and conditions to determine what must be true is:
Deductive Reasoning.
<h2>
Step-by-step explanation:</h2>
Deductive Reasoning--
It is a logical reasoning that starts with a general set of premises or statements and reach to a specific conclusion.
It is different from the inductive reasoning in the way that the inductive reasoning starts with a set of specific set of rules and reach to a general conclusion.
If 17.3% equals 52,900, then
1% equals 52,900/17.3, and
100% equals 52,900/17.3*100 = 305,780.34
Hence, the total amount of doctors is about 305,780
The factoring the equation (a + 1)² - 4b² we get (a+1+2b)(a+1-2b).
<h3>
What is the factoring function of (a + 1)² - 4 b²?</h3>
Given: (a + 1)² - 4b²
Apply Perfect Square Formula, and we get
(a + b)² = a² + 2 a b + b²
(a + 1)² = a² + 2a1+1²
= a² + 2a1 + 1² - 4 b²
simplifying the equation, we get
a² + 2a1 + 1² = a² + 2a + 1
= a² + 2a + 1 - 4b²
Factor, a² + 2a + 1 = (a + 1)²
= (a + 1)² - 4 b²
Simplify 4 b² = (2 b)²
= (a + 1)² - (2b)²
Apply the Difference of Two Squares Formula, and we get
x² - y² = (x + y)(x - y)
(a + 1)² - (2b)² = ((a + 1) + 2b)((a + 1) - 2 b)
simplifying the equation, we get
= ((a + 1) + 2b)(a + 1) - 2 b)
= (a + 1 + 2b)(a + 1 - 2b)
Therefore, the correct answer is (a+1+2b)(a+1-2b).

For this case we want to do the following operation:
-3/5 divided by 7/16 and we can do this:
And then we can simplify and we got:
