Okay hopefully the picture went but I need help foiling this please

- - 2z - 5

Step-by-step explanation:

This is the equation that you started off with:

(x - z - )(x + z + )

You can't really use FOIL on this because that's used in multiplying binomials, and this is a trinomial, but you can still break it up and simplify it this way:

(a + b + c)*(d + e + f) = (a(d + e +f)) + (b(d + e + f)) + (c(d + e + f))

So, applying that idea to the actual equation:

x(x + z + ) -z(x + z + ) - (x + z + )

= x^2 + xz + x -xz -z^2 - z - x - z - 5

= x^2 - z^2 - 2z - 5

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

24/56=hx^7
