Answer:
(B) (7x - 6 ) ( 7x + 6)
Step-by-step explanation:
49x^2 - 36
This is the difference of squares
(7x)^2 - 6^2
We can factor this as
(a^2 -b^2) =(a-b) (a+b)
(7x)^2 - 6^2 = (7x-6) (7x+6)
Answer:
i believe is A
Step-by-step explanation:
Answer:
There are 72 words on the list.
Step-by-step explanation:
If 48 is 2/3 of the total number then we can divide 48 by 2 to get 1/3 of the total which is 24.
All you need to now is multiply 24 by 3 to get 3/3 or the total number which would be 72.
Hope this helps!
Some key definitions:
<u>Reflexive property:</u> angles, line segments, shapes are congruent to themselves. Its easier to think of a shape: if you have a circle, then this circle is equal to itself.
<u>Symmetric property:</u> you can interchange the equal signs of an equation. So think of a=b is the same as b=a, its just the same thing written in a different order.
<u>Transitive property:</u> If a=b, and b=c, then a=c. Basically think of it as a=b=c, all of these variables are the same as each other.
So for the first clue, you have the reflexive property.
The second clue is the symmetric property.
The third clue is the transitive property.
