Expand.<br> Your answer should be a polynomial in standard form.<br> (3c + 2)(c^2-6c-4)
evablogger [386]

Answer:

After expanding the polynomial (3c + 2)(c^2-6c-4) we get  3c^3-16c^2-24c-8

Step-by-step explanation:

We need to expand the polynomial (3c + 2)(c^2-6c-4)

Multiply the terms:

(3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8

So, after expanding the polynomial (3c + 2)(c^2-6c-4) we get  3c^3-16c^2-24c-8

A club has money for a trip. The expenses for the trip are shown below:
KonstantinChe [14]

Answer:

3/100

Step-by-step explanation:

convert these measurements into one unit, I am going to do decimals but you can sue fractions or percentages as well.

1/4 is 0.25

2/5 is 0.4

0.12 is 0.12

20% is 0.2

if you add all these up, it equals 0.97

1- 0.97= 0.03

you therefore have 0.03 of the money left over

this as a fraction is 3/100
