I can someone evaluate this I don’t understand? Question: 8. Evaluate the piecewise-defined function at the indicated inputs.

enot [183]

Answer:

Step-by-step explanation:

Your function is split into 4 parts.

We want to use the piece that includes x=6.

This only included in the inequality that says x is greater than or equal to 5. Since that is, we use the expression that corresponds to that to find f(6).

f(6)=2(6)-6

f(6)=12-6

f(6)=6

Answer:

$f(a) = \frac{(a+5)}{(a-1)}$

Step-by-step explanation:

Given : $f(x) = \frac{(3+x)}{(x-3)}$

In order to find $f(a+2)$ we will substitute $(a+2)$ for $x$ in the given function, that is :

$f(a) = \frac{(3+a+2)}{(a+2-3)}$

$f(a) = \frac{(a+5)}{(a-1)}$

Factorise : 64a cube minus 27b cube minus 144a square b plus 108ab square .

Svetlanka [38]

Answer:

$16a(4a^2-9a)+27b^2(4a-b)$

Step-by-step explanation:

The question is not properly formatted, here is a good format for proper understanding and readability

$64a^3-27b^3-144a^2+108ab^2$

let us first collect/ group like terms

$64a^3-144a^2+108ab^2-27b^3$

we can now bring out the common factors we have

$16a(4a^2-9a)+27b^2(4a-b)$

<em>The simplified expression is </em>

$16a(4a^2-9a)+27b^2(4a-b)$
