Answer:

$\large\boxed{f(x)-g(x)-h(x)=-5x^2+6x+6}$

Step-by-step explanation:

$f(x)=3x+5\\\\g(x)=4x^2-2\\\\h(x)=x^2-3x+1\\\\f(x)-g(x)-h(x)=(3x+5)-(4x^2-2)-(x^2-3x+1)\\\\=3x+5-4x^2-(-2)-x^2-(-3x)-1\\\\=3x+5-4x^2+2-x^2+3x-1\qquad\text{combine like terms}\\\\=(-4x^2-x^2)+(3x+3x)+(5+2-1)\\\\=-5x^2+6x+6$

Answer:

- 5x² + 6x + 6

Step-by-step explanation:

f(x) - g(x) - h(x)

= 3x + 5 - (4x² - 2) - (x² - 3x + 1) ← distribute parenthesis

= 3x + 5 - 4x² + 2 - x² + 3x - 1 ← collect like terms

= - 5x² + 6x + 6 ← in standard form

Alaska has a coastline of about 6.64 thousand miles. Florida has about 1.35 thousand miles of coastline. How many times more mil

victus00 [196]

All you need to do is divide 6.64 and 1.35. you would get 4.91851852. But, you need to round to the nearest tenth so it would actually be 4.9.

The length and

Iteru [2.4K]

Answer:

42 yards

Step-by-step explanation

There are 4 sides to a rectangle. 2 lengths, and 2 widths. That means that you multiply both values by 2 and then add them together, so 40 + 2. A more basic way to think of it is 20+20+1+1. Therefore, the perimeter is 41 yards.
