Answer:

A. x=4 and x= -10

Step-by-step explanation:

x^2 +6× = 40

x^2 +6x -40

(x-4)(x+10)

x-4 = 0

x+10 = 0

x= 4

x=-10

N+ 12 = -24<br><br> Help please
omeli [17]

Answer:

n = -36

Step-by-step explanation:

The answer is -36 because:

1) We first have to subtract -24 and 12 to find n

-24 - 12 = -36

This is because whenever there are two negative signs, multiply it.

Negative x Negative = Positive

We have to do, 24 + 12 which is 36. Finally, we just put the greater number's sign to the answer. 24 is greater than 12, therefore, we put a negative sign before 36.

Hope this helps!
