PLEASE HELP Bidet used a computer algebra system (CAS) to find the quotient of (4x^3+2x^2+3x+5)^2 and x^2+3x+1. Which statement correctly shows a way to enter this problem into a CAS?

A. Division[4x^3+2x^2+3x+5^2, x^2+3x+1]
B. Division[ (4x^3+2x^2+3x+5)^2] [x^2+3x+1]
C. Division[ (4x^3+2x^2+3x+5)^2, x^2+3x+1]
D. Division[2 (4x^3+2x^2+3x+5), x^2+3x+1]

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

c. side angle side. u shares the same sides

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
