The product of (3p-7)(3p+7) is a. 9p^2-49

(3p - 7)(3p + 7) has the form of (a-b)(a+b).
So (a-b)(a+b)= a^2-b^2.
So in (3p - 7)(3p + 7), a=3p and b=7.
So (3p - 7)(3p + 7) = 3p^2 + 7^2 = 9p^2-49.
So (3p-7)(3p+7)= 9p^2 - 49.

You can check your answer (very important):
We'll use p=1.
(3-7)(3+7) = -40
9-49 = -40
The answer has been approved.

Hope this Helps! :)

The results are biased.  

When you go to a particular sporting event and ask someone their favorite sport, they are more likely to respond the sport that they're watching at that moment.  This creates bias.

P(t) = price after t months --> S 
Po = initial price -- P 
r = rate as a decimal 

S = P(.9)^4

Need a little help with one please
Pani-rosa [81]

Answer:

That would be the side-side-side (SSS) postulate, which states that if all the sides of a triangle are in a fixed ratio to all the corresponding sides of another triangle, then the two triangles are said to be congruent.

Step-by-step explanation:

Looking at triangles ABC and DEF, we notice that:

\frac{AB}{DE} = \frac{AC}{DF}=\frac{BC}{EF}

since

\frac{3}{18} = \frac{6}{36}=\frac{7}{42}=\frac{1}{6}

Let me know if you have further questions.

Identify the number of solutions. Y&lt; -1/3x+5, y&gt; -1/3x-1.
Elenna [48]

Answer: C. No solution. ( top shaded. Middle not. Bottom shaded.


Step-by-step explanation:

Given inequalities

y< -1/3x+5 and

y> -1/3x-1.

If we draw graph for y< -1/3x+5 equation, it would be a dotted line and we would shade down the dotted line because we have less than < symbol there.

Now, if we draw graph for second inequality y> -1/3x-1, it would also be a dotted line and we would shade up of dotted line because we have greater  than > symbol there.

Now, we can see that slopes of both dotted lines are same that is -1/3.

So, there would not be any common shaded region.

Therefore, there would not by any solution of the system of inequalities.

And correct option is C option.

C. No solution. ( top shaded. Middle not. Bottom shaded.
