Answer:

Step-by-step explanation:

Did you mean  (y+4)^2 = 2?  " ^ " denotes exponentiation.

Expanding (y+4)^2 = 2, we get y^2 + 8y + 16 = 2, or

y^2 + 8y + 14 = 0

Let's apply the quadratic formula.  First, find the discriminant, b^2 - 4ac:

8^2 - 4(1)(14) = 64 - 56 = 8 (which is the square of 2√2).

Because the discriminant is positive, there are two real, unequal roots (solutions).  They are:

      -8 ± √8

x = -------------- = -4 ± √2

           2

Find the product: (-3)(-100) *
Igoryamba

Answer:

300

Step-by-step explanation:

(-3)(-100)= -3 x -100

A NEGATIVE MULTIPLIED BY A NEGATIVE WILL ALWAYS GET A POSITIVE SO MAKE -3 INTO 3 AND TURN -100 INTO 100.

Now you have 3 x 100 which gets you <u>300</u>

What is -2x + 12 divided by 4
Goshia [24]

Answer:

x=4

Step-by-step explanation:

First set the equation equal to 4:

-2x +12=4

Subtract 12 from both sides:

-2x +12=4

      -12  -12

-2x=-8

Then divide each side by -2 to isolate the x:

-2x/-2=-8/-2

x=4
