Answer:
-3/2 or 1.5
Step-by-step explanation:
5n + 10 = n + 4
5n - n = -10 + 4
4n = -6
n = -6/4
n = -3/2 (or -1.5)

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 " .

First we have to assume that each quarter touched each other. Hence the area of the table not covered by the coins (A) is equal to the total area of the table (At) minus the total area of the coins (Ac). Coins are circle, so
and r =24.26mm. The area of one coin is then 1848.98mm^2. Hence the equation is A = At - xAc where x is the number of coins.
First find the slope, take derivative of both sides with respect to x.
2y dy/dx=3x^2+6x
solve for dy/dx
dy/dx=[3x^2+6x]/2y
plug in given vales of (1,2(
dy/dx=9/4
now you have everything you need to plug into point slope form
y-2=(9/4)(x-1)
answer is y=(9/4)x+(1/4)
