Answer:

x = -1 or x = -3

Step-by-step explanation:

x + 3/x = -4

x² + 3 = -4x

x² + 4x + 3 = 0

(x + 1) (x + 3) = 0

x = -1 or x = -3

check: (-1) + (3/-1) = -1 - 3 = -4

(-3) + (3/(-3)) = -3 -1 = 14

Answer:

x = 10

Step-by-step explanation:

Use the Pythagorean theorem. The sum of the square of the sides is the square of the hypotenuse.

x = √100 = 10

(3m2 + 8 - 3) + (n + 3) <br> Simplified

RUDIKE [14]

Answer:

$\boxed {3m^{2} + n + 8}$

Step-by-step explanation:

Simplify the following expression:

$(3m^{2} + 8 - 3) + (n + 3)$

-Subtract $3$ from $8$ :

$(3m^{2} + 8 - 3) + (n + 3)$

$3m^{2} + 5 + n + 3$

-Add $5$ and $3$ :

$3m^{2} + 5 + n + 3$

$\boxed {3m^{2} + n + 8}$

Therefore, the final answer is $3m^{2} + n + 8$ .
