The horizontal yellow are is : 2(x+3) = 2x + 6
The vertical yellow are is : x(x+2+x) = x(2x+2) = 2x² + 2x
Total area = 2x + 6 + 2x² + 2x = 2x² +4x + 6 (answer B)
2(3x) and 2(-9)
so 2*3x equals 6x and 2*-9 equals -18
6x-18
Given:
The equation is:
To find:
The error in the given equation and correct it.
Solution:
We have,
Taking left-hand side, we get
![[\because a^2-b^2=(a-b)(a+b)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29%5D)
![[\because (ab)^x=a^xb^x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28ab%29%5Ex%3Da%5Exb%5Ex%5D)
It is not equal to right-hand side 
. In the right hand side, there must be a negative sign instead of positive sign.
Therefore, 
.
