How do I solve this equation?
frosja888 [35]

Answer:

x=-3/11

Step-by-step explanation:

(x+3)/5 +2x=0

Multiply both sides by 5 to get rid of the fraction

5*( x+3)/5 +5*2x=0*5

x+3 + 10x =0

Combine like terms

11x +3 = 0

Subtract 3 from both sides

11x+3-3 =0-3

11x = -3

Divide by 11

11x/11 = -3/11

x = -3/11

Find the sum: 4 radical 3 + 11 radical 12
Ksenya-84 [330]

Answer:

26\sqrt{3}

Step-by-step explanation:

We want to find 4\sqrt{3} +11\sqrt{12}. 11\sqrt{12} can be written as 11\sqrt{4*3}=11*\sqrt{4} *\sqrt{3}=11*2*\sqrt{3}=22\sqrt{3}, so we can now write our original equation as: 4\sqrt{3}+22\sqrt{3}.

We can combine like terms: 4\sqrt{3}+22\sqrt{3}=26\sqrt{3}

Hope this helps!
