Answer:

  4 cm

Step-by-step explanation:

The perimeter of the original rectangle is ...

  P = 2(L+W) = 2(4x + x) = 10x

The perimeter of the larger rectangle after we add "a" to each side is ...

  P = 2(L +W)

  = 2((4x+a) +(x+a))

  = 10x +4a = 10x +16

  4a = 16 . . . . . subtract 10x from both sides

  a = 4 . . . . . . . divide by 4

The length added to each side is 4 cm.

% change = (new value - old value)/(old value) * 100%
.. = (9.67 -9.74)/9.74 * 100%
.. = -0.07/9.74 * 100%
.. = -0.7%

The decrease is 0.7%.

15y^-11/3y^-11, show steps I need help please don't understand how to do it.

One may note, you never quite asked anything per se, ahemm, if you meant simplification.

\bf \left.\qquad \qquad \right.\textit{negative exponents}\\\\
a^{-{ n}} \implies \cfrac{1}{a^{ n}}
\qquad \qquad
\cfrac{1}{a^{ n}}\implies a^{-{ n}}
\qquad \qquad 
a^{{{  n}}}\implies \cfrac{1}{a^{-{{  n}}}}\\\\
-------------------------------\\\\
\cfrac{15y^{-11}}{3y^{-11}}\implies \cfrac{15}{3}\cdot \cfrac{y^{-11}}{y^{-11}}\implies 5\cdot y^{-11}\cdot y^{+11}\implies 5\cdot y^{-11+11}
\\\\\\
5y^0 \implies \boxed{5}
