Which statement best describes the polynomial? -24x^7-12x^2-9x+6

a. it is in standard form because the exponents are in order from highest to lowest.
b. it is in standard form because the coefficients are in order from highest to lowest.
c. it is not in standard form because the constant should be the first term.
d. it is not in standard form because it can be further simplified.

if you need just tell me and i will come to the rescue.

step-by-step explanation:

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
