For this case we have the following expression:
 (1 / x + 2) + (1 / x + 3) + (1 / X ^ 2 + 5 + 6)
 Rewriting we have:
 (1 / x + 2) + (1 / x + 3) + (1 / ((x + 2) * (x + 3)))
 By doing common factor we have:
 (1 / ((x + 2) * (x + 3))) * (x + 3 + x + 2 + 1)
 Rewriting:
 (1 / ((x + 2) * (x + 3))) * (2x + 6)
 The sum is:
 ((2x + 6) / ((x + 2) * (x + 3)))
 Answer:
 
((2x + 6) / ((x + 2) * (x + 3)))

Answer:

C) -1

Step-by-step explanation:

(ax+3)²=36

<em>Square root both sides</em>

ax+3=6

<em>Subtract 3 from both sides</em>

ax=3

<em>Put x in</em>

-3a=3

a= -1

C) -1 would work.

Need all these tomorrow!!!!! thank you all soooooOOOOOOooOoOOooOOoO much!!!!!

1.) 6% of 38 1% of 38 = 3.8 ( you just move the decimal placement over by one. 1% * 6 = 6% 3.8 * 6 = 6% 3.8 * 6 = 22.8 6% =22.8 2.) 5% of 90 90/5 = 5% 90/5 = 18 18 = 5% 3.) 15/5 = 9/x 15/5 = 3 3 = 9/x (nine divided by ? is three?....3!) 3 = 9/x(3) 3 = 9/3 3 = 3 x = 3 4.) 1/12 = .8/x Multiply each side by ten. 1/12 * 10 = 5/6 .8/x * 10 = 8/x 5/6 = 8/x Cross Multiply (switch the second numbers around) 5x = 6*8 Simplify 5x = 48 Divide both sides by 5 to get x by itself 5x/5 = x 48/5 = 9.6 *Whoo last problem lol* 5.) A three liter bottle costs $2.97 what is the unit rate. Well the unit is the object we're talking about, in this case a liter bottle. The unit rate is how much it costs or is per unit. Now that that's out of the way... 3L = 2.97 Like the other problems we want to get x by itself, so we'll divide by three) 3L/3 = L 2.97/3 = .99 L = .99 The Unit Rate is $0.99 per liter bottle. Hope this helped :)
