<u>Answer:</u>

The simplest form of  \frac{t^2-4t-32}{t-8} is t+4.

<u>Step-by-step explanation:</u>

We are given an expression \frac{t^2-4t-32}{t-8}.

Factorizing the numerator such that the factors when multiplied give a product of -32 and when added give a result of -4:

\frac{t^2-4t-32}{t-8}

=\frac{t^2-8t+4t-32}{t-8}

= \frac{t(t-8)+4(t-8)}{t-8}

=\frac{(t+4)(t-8)}{t-8}

= t+4

Since the denominator is t-8 in this expression, therefore t\neq 8 or it will be equal to zero which will make the overall value of the fraction undefined.

1. Factor the expression t^2-4t-32:

t^2-4t-32=(t-8)(t+4).

2. Since t-8 is placed in the denominator of the given expression, then t\neq 8.

3. Now the expression can be simplified:

\dfrac{t^2-4t-32}{t-8}=\dfrac{(t-8)(t+4)}{t-8}=t+4.

Answer:

  9t^3 +t^2

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of the sides. The side lengths are represented by the polynomials shown, so the perimeter (P) is their sum:

  P = (4t^3 -5) + (4t^3 -5) + (t^2 +9) + (t^3 -t^2 -11) + (t^2 +12)

Rearranging to group like terms:

  P = (4t^3 +4t^3 +t^3) + (t^2 -t^2 +t^2) + (-5 -5 +9 -11 +12)

  P = 9t^3 +t^2

The perimeter of the figure is represented by the polynomial 9t^3 +t^2.

x = amount of rent paid per half year

2x = amount of rent paid annually

y = amount spent on groceries per quarter

4y = amount spent on groceries annually

z = amount spent on a transit pass monthly

Set up the problem like this: x - 4 + 8 = 44

x-4+8=44             (8-4)

x+4=44

  -4   -4                (subtract 4 from both sides)

x=40
