PtichkaEL [24]3 years ago

The answer is 1/(x+4)
Explanation:
You would factor out the denominator
So,
(X-4)(x+4)=x^2-16
So, x-4/(x+4)(x-4)
Then x-4 cancels each other out from the numerator and denominator
Leaving 1/x+4

<h3>Answer:</h3>

B (2m^3−4p^5)(2m^3+4p^5)

<h3>Step-by-step explanation:</h3>

The factoring of the difference of squares is the product of the sum and difference of the squared terms.

... a² -b² = (a -b)(a +b)

Here, you have ...

  • a = 2m^3
  • b = 4p^5

So, the factoring is the product of the sum and difference of these values:

... (2m^3 -4p^5)(2m^3 +4p^5) . . . . . . matches selection B

6(x-3)-10=2(x+3) please help me solve this equation ​
8090 [49]
6(x - 3) - 10 = 2(x + 3)
6x - 18 - 10 = 2x + 6
6x - 28 = 2x + 6
add 28 to both sides of the equation
6x = 2x + 34
subtract 2x from both sides of the equation
4x = 34
divide 4 from both sides of the equation
x = 8.5

Determine whether the triangles are similar. If so, write a similarity statement and name the postulate or the theorem you used.
neonofarm [45]
The first pair of triangles are similar.

Triangle ABC is similar to Triangle PQR.

I used the SSS theorem of congruency.

( side - side - side) since I knew the sides were equal I knew that they were congruent.

----------------------------------------------------------

The second pair of triangles are similar too.

Triangle ABC is similar to Triangle DEF.

I also used the SSS theorem of congruency.

Since I knew what the sides were, I did some calculations and they all equalled 6...

----------------------------------------------------------

I hope that helps you out!! Any more questions??

At Joe's Grocery, you can buy hot dogs only in packages of 4 or packages of 7. As a result, you can't buy exactly 9 hot dogs sin
Inessa05 [86]

Answer:

29

Step-by-step explanation:

Hot Dog packages

4 = 2 *2

7 = 1 * 7

To determine, the largest possible number of hot dogs that you can't get exactly by buying these hot dogs is to determine the LCM ( lowest common multiple of 4 and 7 ) and add 1 to it

LCM of 4 and 7  = 1 * 2 * 2 * 7  = 28

Highest number that combining 7 and 4 packages can't give = 28 + 1 = 29
