The area of a rectangle is L x W, so 9(5+x) is the formula for the area in factored form. It can be simplified to 45+9x
3/4 as you are paying for what is not discounted
Answer:
6(10)+5x=180
Step-by-step explanation:
The grocery store received a crate of 180 pound...
So, the whole amount is 180..
The crate contains six 10 pound bag of potato plus an unknown number of 5pound bag of potato....
So if we think, that the unknown number is x the equation would be
6(10)+5x=180
Hope ya find this helpful..
Ew. Composition of functions. Ok, f(g(x)) is what that fancy notation means. So, you would take g(x) & substitute that into wherever x is in f(x).
So we get something crazy like
f(x)= 4 - (.5x - 2)^2
Now, we foil out the squared quantity:
f(x)= 4 - (.25x^2 - x - x + 4)
Can you believe they call that simplification?
f(x)= 4 - .25x^2 + 2x -4
Almost there...
f(x)= -.25x^2 + 2x
Hope this helps!
