It's impossible to solve all that you give but I think I can help you. There are many different sites which have soft that can solve tasks like this. Just enter what you need in search bar and follow the first link you see.
I don't know how to solve this but you can go to desmos.com and it will graph it for you.
Hope this helps make your life easier!
it's C because the floor area is 120 square feet and the walls are 8 feet so if you multiply 120 × 8 you get 960.
It's the last answer. Think about when you move a point on a graph left 4 spaces it's on the x axis. Because it's going left it's going towards the negative numbers hence minus and not plus. some concept for the y axis.
we have
(a+b)(3a-b)(2a+7b)
step 1
Solve
apply distributive property
(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2
step 2
Multiply (3a^2-4ab-b^2) by (2a+7b)
6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3
answer is
<h2>6a^3+13a^2b-30ab^2-7b^3</h2>
