Answer:

B

Step-by-step explanation:

16 x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b), thus

16x² - 49

= (4x)² - 7²

= (4x + 7)(4x - 7) → B

Answer:

B

Step-by-step explanation:

There is no number between 16x and 49. So only think about the number being squared for 49; which is 7.

Then 49 is negative, so you must have both positive and negative signs in both parenthesis. Otherwise, positive times positive is positive, and negative times negative is also positive.

4x4 is 16. That's why you put fours in front of Xs.

I am sorry for getting this wrong (if i did)

Answer:

Jose can invite 16 friends.

Step-by-step explanation:

For roller skating, the skate rentals charge $2.50 per person.

Jose has to invite friends and wants to spend a total of $50.

$50 / $2.50 = 20

So, for $50.00, 20 people can enjoy roller skating.

Out of these 20 people, one will he Jose himself and 3 will be the adult chaperones.

20 - 4 = 16

Therefore, Jose can invite 16 friends for roller skating.

Jose can invite 46 of his friends, given that there isn't tax. Because with a ticket costing $2.50 a person, and he at least knows that 50 people can go, and that 4 people are planning to, and are going to skate already.
