HELP PLEASE ASAP!!!!!!!!!!!!!!
Nesterboy [21]
A. Since the area of a triangle is equal to A = 0.5bh, we just plug in numbers given to us:
A = \frac{1}{2}bh= \frac{1}{2}(2x+7)(4x+6)= \frac{1}{2}(8x^2+40x+42)=4x^2+20x+21

So, that's your answer.

B. The answer is a 2nd-degree trinomial because it has three terms and it's highest exponent is 2.

C. Polynomials are closed under multiplication because if you multiply two polynomials, you get another polynomial (except if you multiply by the inverse which is excluded anyways).

Your cellphone plan gives you 500 minutes monthly. If you have used 310 minutes already and there is a week left this month, how
Nitella [24]
In this case, you already used 310 minutes out of 500 minutes monthly. So the remaining time for your cell phone should be: 500 minutes -310 minutes= 190 minutes.
You still have 1 week this month, that means the 190 mins time must be divided into 1 week or 7 days. Then the duration you of cell phone use for each day should be: 190 minute/7days= 27.14 minutes/day
