Are negative numbers prime or composite?

2 answers:

5 0

depends on the value of said negative number. even if they are negative it has nothing to do with them being prime or composite. 3, for example, will always be a composite number. everything that can be multiplied evenly by 3 will also always be a composite number.

Find the solution set. (x+7)(x+7)=0

levacccp [35]

For this case we must find the solution of the following expression:

$(x + 7) (x + 7) = 0$

If we isolate a term and we equate to zero, we have:

$x + 7 = 0$

Subtracting 7 on both sides of the equation we have:

$x + 7-7 = 0-7\\x = -7$

Thus, the solution of the expression is given by:

$x = -7$

ANswer:

$x = -7$

mart [117]

Answer: He bought 6 pounds of coffee.

Step-by-step explanation:

Money he have = 70

money he used to buy = 70.00 - 23.62 = 46.38

7.73 dollar = 1 pound

1 dollar = 1/(7.73) = 100/773 pound

46.38 dollar = (100/773) * 46.38 = 6 pound
