What are the solutions of the equation (2x + 3)2 + 8(2x + 3) + 11 = 0? Use u substitution and the quadratic formula to

Assoli18 [71]

Answer:

x= −41 /20

Step-by-step explanation:

(2x+3)(2)+8(2x+3)+11=0

(4x+16x)+(6+24+11)=0(Combine Like Terms)

20x+41=0

Step 2: Subtract 41 from both sides.

20x+41−41=0−41

20x=−41

Step 3: Divide both sides by 20.

20x /20 = −41 /20

x= −41 /20

Find -2/3 divided by 4/6<br> -1<br> 4/9<br> -9/4<br> 1

nalin [4]

Answer:

-1

Step-by-step explanation:

The given expression is:

$-\frac{2}{3}\div \frac{4}{6}$

We multiply by the reciprocal to get:

$-\frac{2}{3}\times \frac{6}{4}$

We factor so that we can cancel easily:

$-\frac{2}{3}\times \frac{3\times 2}{2\times 2}$

Cancel the common factors to get:

$-\frac{1}1}\times \frac{1\times 2}{1\times 2}$

This simplifies to:

$-1$
