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 " .

Have a nice day...
(2,3)(4,4)
slope = (4 - 3) / (4 - 2) = 1/2
y = mx + b
slope(m) = 1/2
(2,3)...x = 2 and y = 3
sub and find b, the y int
3 = 1/2(2) + b
3 = 1 + b
3 - 1 = b
2 = b
ur equation is : y = 1/2x + 2...but we need it in standard form
y = 1/2x + 2
-1/2x + y = 2 ...multiply by -2
x - 2y = -4 <== standard form
