Answer:

4. B. 7

5. 30

Step-by-step explanation:

4. The perimeter is the sum of the side lengths:

29 = (x+5) +(2x -3) +(x -1) = 4x +1

28 = 4x . . . . subtract 1

7 = x . . . . . . divide by 4

5. Add 18 to both sides of the equation.

9x -11 +18 = 12 +18

9x +7 = 30

Rewrite, differentiate and simplify:<br> 3/(2x)^3

Llana [10]

$\frac{dy}{dx}$ = - $\frac{9}{8x^{4} }$

let y = $\frac{3}{(2x)^{3} }$ = $\frac{3}{8}$ $x^{-3}$

differentiate using the power rule

$\frac{d}{dx}$ ( $ax^{n}$ ) = na $x^{n-1}$

$\frac{dy}{dx}$ = - $\frac{9}{8}$ $x^{-4}$ = - $\frac{9}{8x^{4} }$
