Which polynomial is in standard form?

Choice D)  23x^9 - 12x^4 + 19

A single variable polynomial is in standard form when the exponents are decreasing as you move from left to right. The exponents 9, 4, 0 go downhill so to speak.

The term 23x^9 is the leading term with 23 as the leading coefficient. The degree of this polynomial is 9 which is the largest exponent. This polynomial is a trinomial as there are 3 terms here.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
