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

Reduce any fractions to lowest terms.Don’t round your answer, and don’t use mixed fractions

DENIUS [597]

Answer:

t < $\frac{38}{17}$

Step-by-step explanation:

Add '5t' to both sides

12t - 2 +5t < -5t +36 +5t

17t -2 < 36

Add ' 2' to both sides

17t -2 +2 < 36 + 2

17t < 38

Dividing '17' on both sides

$\frac{17t}{17}$ < $\frac{38}{17}$
