The answers are 2. B, 3. D, 4. C, and 5. A.

Step-by-step explanation:

Step 1:

For question 2. 4+4n = -12.

We subtract both sides by 4 to get

4+4n-4 = -12-4, 4n = -16, n = -4

For question 3. 4n=-12.

We divide the entire equation by 4 to get

\frac{4n}{4} = \frac{-12}{4} , n = -3.

Step 2:

For question 4. \frac{n}{4} = -12.

We multiply both sides by 4 to get

\frac{n}{4} (4)= -12(4).

n = -48.

For question 5. \frac{n}{4} -4 = -12.

We add 4 to both sides to get

\frac{n}{4} -4 +4= -12+4, \frac{n}{4} = -8.

n = -32.

So the answers are 2. B, 3. D, 4. C, and 5. A.

The LCD is x^2+3x+2 = (x+2)(x+1)
The goal is to get each fraction to have the denominator be equal to the LCD
Afterward we can add the fractions

x/(x^2+3x+2) + 3/(x+1)
x/((x+2)(x+1)) + 3/(x+1)
x/((x+2)(x+1)) + (3(x+2))/((x+2)(x+1))
(x+3(x+2))/((x+2)(x+1))
(x+3x+6)/(x^2+3x+2)
(4x+6)/(x^2+3x+2)

--------------------------------------------------

Final Answer: 4x+6

Note: you can factor 4x+6 to get 2(2x+3)

Stiind ca triunghiurile sunt asemenea si c= 5 calculati lungimea laturilor indicate
slava [35]

Answer:

a=8\\b=10\\c=5

Step-by-step explanation:

In the given image, you can observe we have two right triangles.

Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.

If the triangles are similar, we can define the following proportion between sides.

\frac{4}{a} =\frac{3}{6}\\ 24=3a\\a=\frac{24}{3}\\ a=8

Now we use the Pythagorean's Theorem to find each hypothenuse.

c^{2} =4^{2} +3^{2}\\ c=\sqrt{16+9}=\sqrt{25} \\ c=5

b^{2} =8^{2} +6^{2}\\ b=\sqrt{64+36}=\sqrt{100}\\  b=10

Therefore, the missing sides are

a=8\\b=10\\c=5

Find the value of x in each case:
Zanzabum

Answer:

x=30\°

Step-by-step explanation:

<u>Find the measures of interior angles in each triangle</u>

Triangle BGC

m

The measures of triangle BGC are 90\°-60\°-30\°

Triangle CGH

we know that

m -----> by consecutive interior angles

we have that

m

so

m

m

substitute

m

we have

m

m

m

remember that

m

60\°+2x+180\°-4x=180\°

60\°=2x

x=30\°

The measures of triangle CGH are 60\°-60\°-60\°

Triangle GHE

m< EGH=90\°-2x=90-2(30\°)=30\°

m< GHE=4x=4(30\°)=120\°

remember that

m

substitute and solve for m<GEH

30\°+120\°+m

150\°+m

m

The measures of triangle GHE are 30\°-120\°-30\°
