Answer:

$x=-1$

Step-by-step explanation:

STEP 1: Factor x ^2 − 8 x + 12 using the AC method.

$\frac{4}{(x-6)(x-2)} =\frac{x}{x-2} +\frac{1}{x-6}$

STEP 2: Find the LCD of the terms in the equation.

$(x-6)(x-2)$

STEP 3: Multiply each term by ( x − 6 ) ( x − 2 ) and simplify.

$4=x^2-5x-2$

STEP 4: Solve the equation.

$x=6,-1$

STEP 5: Figure out the answer.

$x=-1$

Answer:

Step-by-step explanation:

surface area = 2πrh + 2πr²

where r = 4 km radius

h = 8 km

<u>plugin values into the formula</u>

surface area = 2πrh + 2πr²

= 2π (4) 8 + 2π (4)²

= 201.062 + 100.531

= 301.593 km²

write an equation in y=mx+b for a line that passes through (3,-4) & has a slope of -3. you can write it in point-slope and c

dedylja [7]

Y = -3x + b
Plug in point
-4 = -3(3) + b
-4 = -9 + b, b = 5
Solution: y = -3x + 5

Which of the following correctly justifies statement 4 of the two-column proof?

slavikrds [6]

Answer:

D.Transitive property of equality

Step-by-step explanation:

We are given that segment JK is parallel to segment LM

We have to prove $\angle 3=\angle 6$

We have to find which option correctly justifies the statement 4 of the two - column proof.

1.Statement : JK is parallel to segment LM

Reason: Given

2. $\angle 7\cong \angle 6$

Reason: Vertical angles theorem

3. $\angle 3\cong \angle 7$

Reason:Corresponding angles theorem

4. $\angle 3\cong \angle 6$

Reason: Transitive property of equality.

If a=b and b=c then a=c

Hence, option D is true.

Answer:

12 $\sqrt{6}$ + 8 $\sqrt{15}$ + 12 + 4 $\sqrt{10}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Given

(4 $\sqrt{3}$ + 2 $\sqrt{2}$ )(3 $\sqrt{2}$ + 2 $\sqrt{5}$ )

Each term in the second factor is multiplied by each term in the first factor, that is

4 $\sqrt{3}$ (3 $\sqrt{2}$ + 2 $\sqrt{5}$ ) + 2 $\sqrt{2}$ (3 $\sqrt{2}$ + 2 $\sqrt{5}$ ) ← distribute both parenthesis

= 12 $\sqrt{6}$ + 8 $\sqrt{15}$ + 12 + 4 $\sqrt{10}$
