Answer:

t+4, t≠8

Step-by-step explanation:

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

The value of t must not be one that makes the denominator zero, hence must not be 8.

We can describe 3x 2 as an expression. How can we describe the parts of the expression ?

sattari [20]

Answer:

As you can see, x is a variable in both 3x 2 and 7x, and the variable x is multiplied by a number. In the first term, 3x 2, 3 is multiplied by the variable, so 3 is a coefficient. With 7x, 7 is multiplied by the variable. 7 is therefore a coefficient.

Sergeu [11.5K]

Answer:

$w^{5}$ , w to the power of 5

Step-by-step explanation:

We can distribute the 7’s to get:
7b - 7a - 7b - 7a

Combining like terms, we have:
