Step-by-step explanation:
25 - 2(5 + 4x)
= 25 - 10 - 8x (Distributive Property)
= 15 - 8x.

Perimeter of a square =128cm
Let
the side of the square =a
- As we know that in a square
![\boxed{\sf Perimeter=4a}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20Perimeter%3D4a%7D)
![\hookrightarrow\sf 4a=128](https://tex.z-dn.net/?f=%5Chookrightarrow%5Csf%204a%3D128%20)
![\hookrightarrow\sf a=\dfrac {128}{4}](https://tex.z-dn.net/?f=%5Chookrightarrow%5Csf%20a%3D%5Cdfrac%20%7B128%7D%7B4%7D)
![\hookrightarrow\bf a=32](https://tex.z-dn.net/?f=%5Chookrightarrow%5Cbf%20a%3D32)
We know that in a square
![\boxed {\sf Area=(a)^2}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Csf%20Area%3D%28a%29%5E2%7D)
![\looprightarrow\sf Area=(32)^2](https://tex.z-dn.net/?f=%5Clooprightarrow%5Csf%20Area%3D%2832%29%5E2)
![\hookrightarrow\bf Area=1024cm^2](https://tex.z-dn.net/?f=%5Chookrightarrow%5Cbf%20Area%3D1024cm%5E2%20)
![\therefore\sf Area\:of\:the\:square\;is\:1024cm^2.](https://tex.z-dn.net/?f=%5Ctherefore%5Csf%20Area%5C%3Aof%5C%3Athe%5C%3Asquare%5C%3Bis%5C%3A1024cm%5E2.)
Answer:
There are two solutions for x;
x = 0
x = ![-\frac{3}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B2%7D)
