You would subtract 4 from both sides. Then it would be 3n = 3. You would then divide each side by 3. The answer you would get is n = 1.

#4)

{ A}

Triangle ABC is congruent to triangle YXZ. How do I know this?

Look at the angles and adjacent (bottom) line.

Because Angle A and Angle Y are both equal to (what I believe says) 78 degrees, they are equal.

Next, Angle B is equal to Angle X because it is the angle that connects the adjacent (bottom) line and the hypotenuse (top line). Even though they have no measurements or tick marks, it's the process of elimination.

Finally, Angle C and Angle Z. We know that these are equal do to their degree similarity of (what I think is) 65.

{B} Triangle ABC is congruent to Triangle RSQ. How do I know this?

Because Angle A is congruent to the only other angle there, Angle R.

Next, B and S are congruent. If you think of them as angles, then you can see that "angle" b is connected to the leg of AB and BC. AC has one tick mark, as does RS. BC has no tick or anything to note it's congruence. So because Point be is stick in between a leg with one tick and one leg with no tick, look for the similarity in triangle RSQ. The similarity showing as S. You should understand enough now to know how I got how C and P are congruent.

#5) Sadly I cannot read the diagram they provide, so I cannot help with it.

#6) The length of BC: ? The length of XZ: ? Measure of Angle BZX: 55 degrees.

QUESTION POSTED AT 01/04/2020 - 01:16 PM

Well you have to use one of the logarithm laws

b * ln (x) = ln (x^b)

So

2 ln (2x + 5) = 8

ln [(2x+5)^2] = 8

So now if we do e^x on both sides and we say that x is going to be what either side equals like this

e^(ln [(2x+5)^2]) = e^8

We we know that

e^[ln (x)] = x so

[(2x+5)^2] = e^8

take square root of both sides

2x + 5 = e^4. and -(2x+5) = e^4

2x = e^4 - 5. and -2x = e^4 + 5

x = (e^4 - 5)/2 and x =(e^4 + 5) / -2

now just use a calculator to solve

b * ln (x) = ln (x^b)

So

2 ln (2x + 5) = 8

ln [(2x+5)^2] = 8

So now if we do e^x on both sides and we say that x is going to be what either side equals like this

e^(ln [(2x+5)^2]) = e^8

We we know that

e^[ln (x)] = x so

[(2x+5)^2] = e^8

take square root of both sides

2x + 5 = e^4. and -(2x+5) = e^4

2x = e^4 - 5. and -2x = e^4 + 5

x = (e^4 - 5)/2 and x =(e^4 + 5) / -2

now just use a calculator to solve

QUESTION POSTED AT 01/04/2020 - 01:15 PM

Yes you are right it's C)

Notice that f(-2) = (-2)³ +2( - 2)² + 4(-2) + 8 =0

Then x³+2x²+4x+8 is divisible by (x+2)

Perform this division & you will get:

x³+2x²+4x+8 = (x+2)(x²+4)

The root of (x+2) is the value that render it nil, that is x=-2

The root of (x²+4) are imaginary (not real) because

x²+4 =0 ==> x² = -4 & x=√-4 or x= 2i (nor real).

Hope you understood the reasoning
