√9a^2 + √49b - a + √b<br><br><br> a. 2b + 8 √a<br><br> b. 2a - 8 √b<br><br> c. 2a + 8 √b
Firdavs [7]
The correct answer:
______________________________________________________
Explanation:
______________________________________________________
Assuming you mean:

" √(9a²)  +  (√49b)  −  a  +  √b " ;

Simplify the expression:
_________________________________________________________

Note that:  " √(9a²) = 3a " ;

                   "√(49b) = 7√b " ;   

And we write the expression

   →  " 3a  +  7√b  −  a  + √b " ; 

Combine the "like terms:

   " + 3a − a  =  2a " ;

   " +  7√b  +  1√b   =  8√b " ; 

Rewrite:  
________________________________________________________
    " 2a  +  8√b " ;  which is:  Answer choice:  [C]:  " 2a  +  8√b " .

Please help me answer this equation
krok68 [10]

Answer:

Step-by-step explanation:

What you do is try to find l by using the given information.

We can start by saying that

A=L*W

Now it's easy algebra

Divide both sides by W

L=A/W

Area and length are given .

A=((m^3-3m+2)/2m^2-7m+3)/(m^3+m-2)/(2m^3+3m-2)

Try to work it out if you can't then tell me in the comments we'll figure it out.

(x + 12)2 + (y+13)2 = 36 <br><br> What’s the steps to get the center and the radius?
Anon25 [30]

Step-by-step explanation:

{(x + 12)}^{2}  +  {(y + 13)}^{2}  =  36 \\ {(x + 12)}^{2}  +  {(y + 13)}^{2}  =   {6}^{2}  \\ equating \: it \: with \:  \\  {(x  - h)}^{2}  +  {(y  - k)}^{2}  =   {r}^{2} \\  - h = 12 \implies \: h =  - 12 \\  - k= 13 \implies \: k =  - 13 \\ \therefore \: center \:  = (h, \:  \: k) =  ( - 12, \:  \:  - 13)    \\ \:  \:  \:  \: {r}^{2}  =  {6}^{2} \implies \: radius \: (r)=  6 \: units
