Please help! write and simplify an expression for the area of the triangle. the directions are on the file. thank youuu

Look below:)

Step-by-step explanation:

Area of triangle formula: (bh)/2

Where b=base

And h=height

Lets substitute b as 6x^4 and h as x^2

(6x^4*x^2)=6x^8

6x^8/2=3x^8

The expression : (6x^4*x^2)/2

Name: Quartic

3x^8

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
