Answer:

No

Step-by-step explanation:

6a + 12  =? 3(3a + 4)

Distribute

6a+12 =? 3*3a + 3*4

6a+12 =? 9a +12

No

The expressions are not equivalent

Answer:

No, these expressions aren't equivalent.

Step-by-step explanation:

They aren't equivalent because you can't simplify the expression 6a+12 so 3(3a+4) isn't equivalent. Hope this helps! :)

Carlos is investing his money. He thinks that he should make nine dollars for every $100 he invests. How much does he expect to
Semenov [28]

Answer:

Carlos expect to make <u>$540</u> on an investments of $6000.

Step-by-step explanation:

Given:

Carlos thinks that he should make $9 for every $100 he invests.

Now, to get the amount Carlos expect to make on an investments of $6000.

Let the amount he expect to make on an investments of $6000 be x.

As, Carlos thinks that he should make nine dollars for every $100 he invests.

<em>So, $100 is equivalent to $9.</em>

<em>Thus, $6000 is equivalent to </em>x.<em />

Now, to get the amount using cross multiplication method:

\frac{100}{9} =\frac{6000}{x}

<em>By cross multiplying we get:</em>

<em />100x=54,000<em />

<em>Dividing both sides by 100 we get:</em>

x=540.

Therefore, Carlos expect to make $540 on an investments of $6000.

Let z =38 (cos(pi/8)+ i sin(pi/8)) and w = 2 (cos( pi/16 ) + i sin(pi/16))
mario62 [17]

Answer:

zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )

Step-by-step explanation:

Given

z =38 (cos(\frac{\pi}{8})+ i sin(\frac{\pi}{8}) and

w = 2 (cos(\frac{\pi}{16} ) + i sin(\frac{\pi}{16})

Required

Determine zw

Given that:

x = v_1(cos(a) + isin(a)) and y = v_2(cos(b) + isin(b))

x * y = (v_1 * v_2)*((cos(a+b) + isin(a+b))

So, we have:

zw=(38 * 2) * (cos(\frac{\pi}{8} + \frac{\pi}{16}) + isin(\frac{\pi}{8} + \frac{\pi}{16}))

zw=76 * (cos(\frac{2\pi + \pi}{16})+isin(\frac{2\pi + \pi}{16}))

zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )

Determine if x + 2 is a factor of p(x) = x ^4 + 3x^ 3 + 4x ^2 - 8 and explain why.
zlopas [31]
X^4+ 3x^3+4x^2-8 |   x+2   =  x^3+x^2+2x-4
 -x^4-2x^3
-----------------------     
         x^3+4x^2-8
         -x^3-2x^2
-------------------------
                 2x^2-8
                 -2x^2-4x
                --------------
                  -4x-8
                    4x+8
----------------------------
                      / /

is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8
