Answer:
9 + 7n - 3 ;
61 ;
Step-by-step explanation:
Let the number = n
9 + 7*n - 3
Hence, the expression is :
`9 + 7n - 3
If the number,n = 8
The value of the expression becomes :
9 + 7(8) - 3
8 + 56 - 3
= 61

Say b, initial price, + 20,000.
y, price after x years = m years + 20,000.
m would be negative because the price would decline after x years.
<span>3y^2 • 4x^2y • 5x = (3*4*5) * (</span><span>y^2 * y) * (</span><span>x^2*x) = 60 * y^3 * x^3 = 60 (xy)^3
