Answer:
$31.5
Step-by-step explanation:
Intrest = P. A. * Intrest Rate * Time
Intrest = 600 * 5.25 /100 = 31.5
x^2-3x-y+16?
simplest form already, but can be converted into a proper polynomial.
x^2-3x-y+16
l = 2w-3
P = 2(l+w)
substitute in for l
P = 2(2w-3 +w)
combine like terms
P = 2(3w-3)
P = 6w-6
P(w) = 6(w-1)
