fenix001 [56]

Answer:

the requirements are missing:

  1. express the height of the rectangle in terms of w
  2. express the area of the rectangle in terms of w

1) the height of the rectangle is:

w + h + h + w = 500 + w

2w + 2h = 500 + w

2h = 500 + w - 2w = 500 - w

h = (500 - w) / 2 = 250 - 0.5w

2) the are of the rectangle is:

w x h = w x (250 - 0.5w) = 250w - 0.5w²

√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 " .
