Step-by-step explanation:

4 +  \frac{2}{3}  =  \frac{3 \times 4 + 2}{3}  =  \frac{14}{3}  = 4 \frac{2}{3}

\frac{67}{71}  \times  \frac{381}{399}  =  \frac{67 \times 381}{71 \times 399}  =  \frac{25527}{28329}  =  \frac{8509}{9443}

\frac{684}{795}  \div  \frac{24}{37}  =  \frac{684}{795}  \times  \frac{37}{24}  =  \frac{25308}{19080}  = 1.33

Identify the polynomial that is the difference of two squares.
Nookie1986 [14]
We know that

 The difference of two squares<span> is a squared number subtracted from another squared number. Every difference of squares may be factored according to the identity</span>
<span>
(A</span>²-B²)=(A+B)*(A-B)
<span>so 

the answer is 
</span><span>49m2 − 81n4

</span>49m2 − 81n4=(7m+9n²)*(7m-9n²)

HELP please.
Scorpion4ik [409]

Answer:

C

Step-by-step explanation:

Here, originally, we are told that the point Q has coordinates (-2,1)

Now, its dilated point has the coordinates (-8,4)

what we can observe here is the the shape original polygon was dilated by a factor of 4 to give the image

Now the point R’ is (0,8)

To get the point R , we simply divide each coordinate by 4

Thus, we have (0/4 , 8/4)

This is same as option C
