I know b is James, Olivia, Feng, Carmela
A) 5x⁴-8 <----- the tell-tale guy is the exponent of the variable, is 4, so the degree is 4, 5x then minus then 8, two terms, a BInomial
b) 4a²-2a-16 <---- same tell-tale guy, a² has a higher exponent than say "a", so, the degree is the higher exponent, degree of 2
it has 3 terms, thus is a TRInomial
c) 9m³ <---- well, is the only term, variable exponent is 3, so, degree of 3
only one term means is a MONOmial.
Discounted price before sales tax = 75/100 x (40 + 24 + 18 x 3) = 3/4 x (64 + 54) = 3/4 x 118 = $88.5
Total price inclusive of sales tax = 107/100 x 88.5 = $94.69
Ratio being 12in./1ft.
3 inches is not one foot. it's 1/4 of a foot. 3in./1/4ft.
3 feet = 36 inches.
36in./3ft.
Hope This Helped! Good Luck!
