2x^2 + 14x = -12

Step 1: Subtract -12 from both sides.

2x^2 + 14x - (-12) = -12 - (-12)

2x^2 + 14x + 12 = 0

Step 2: Factor the left side of the equation.

2(x + 1)(x + 6) = 0

Step 3: Set Factors equal to 0.

x + 1 = 0 or x + 6 = 0

x = -1 or x = -6

Answer:
x = -1 or x = -6

Hope this helps. : )

sdas [7]

Answer:

see below

Step-by-step explanation:

12 banana muffins, 10 chocolate muffins, 6 blueberry muffins, and 7 vanilla muffins.

The total number of muffins is 35 muffins

P(vanilla) = number of vanilla/ total

               = 7/35

               = 1/5

This is not likely to occur so it is an unlikely event

The area of a rectangular flower bed is 24 square feet. The perimeter of the same flower bed is 22 feet. What are the dimensions
Vesna [10]

Answer:

3 ft by 8 ft

Step-by-step explanation:

We were given the area as 24 square feet which means that

L×w= 24....eqn(1)

We were given the perimeter as 22 square feet which means that

22= 2(L +w).......eqn(2)

If we divide both cause by 2 in eqn(2) we have

11= L+ w .....eqn(3)

W= 11-L.........eqn(4)

Substitute eqn(4 into eqn(1)

L× (11-L)=24

-L^2 +11L-24=0

If we factorize

(L-8)(L-3)

L=3 or 8

From eqn4)

W=11-L

At L=3

W=11-3=8

Hence, the dimension is 3 ft by 8 ft

Please help my brain is melting.....

The answer is D. If you plug in -6 for x (the x-value where the asymptote lies), only this equation will yield 1/0 for x=6. This means that D is the correct answer.
