Answer:

-2. 46

- 9.54

Step-by-step explanation:

2x²+12x-7=0
2x²+12x+18= 25
2*(x²+6x+9)=25
2*(x+6)²= 5²
x+6= 5√2/2 ⇒ x= 5√2/2 -6 ≈ -2. 46
x+6= -5√2/2 ⇒ x= -5√2/2 -6 ≈ - 9.54

Maurinko [17]

Answer:

36.36% probability that she gave birth to quadruplets

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcoes.

Desired outcomes:

Giving births to quadruplets.

She has 4 sets of quadruplets.

So $D = 4$

Total outcomes:

At least 3 children(triplets).

7 sets of triplets and 4 sets of quadruplets.

So $T = 7 + 4 = 11$

Probability:

$p = \frac{D}{T} = \frac{4}{11} = 0.3636$

36.36% probability that she gave birth to quadruplets

Solve x − 2y = 3 for x.

wolverine [178]

Answer:

$x=2y+3$

Step-by-step explanation:

So we have the equation:

$x-2y=3$

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

$(x-2y)+2y=(3)+2y$

On the left, the 2y cancel. Simplify the right:

$x=2y+3$

And we're done!
