This is false, because the equation is then 12=2, which is incorrect.

Hope this helps!

1. Solve
8 + 4 = -5 + 7
12 = 2

Obviously 12 doesn't equal 2 so the equation is false. Here are the definitions:
True: The equation is true.
Example: 2 =2

False: The equation is false or not true.
Example: -2 = 2

Open: The equation is true or false depending on what the variable is.
Example: 2x = 2

Area of the entire rectangle $=x^2+10x+24$

Solution:

Area of the blue box = length × width

$=x\times x$

Area of the blue box $=x^2$

Area of the pink box = length × width

$=4\times x$

Area of the pink box $=4x$

Area of the green box = length × width

$=6\times x$

Area of the green box $=6x$

Area of the orange box = length × width

$=6\times 4$

Area of the orange box = 24

Total area of the rectangle $=x^2+4x+6x+24$

$=x^2+10x+24$

Area of the entire rectangle $=x^2+10x+24$
