Step-by-step explanation:
Like terms are are terms whose variables (and their exponents such as the 2 in x 2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.
So like in your picture x and x would be like terms... your picture helps as well to identify your like terms because your like terms have the same background color to there particular rectangle.
I think 2 is the answer i might be wrong
The area of the rectangle is defined as its <em>length</em> multiplied by its <em>width</em>. This rectangle has a length of 3 ft and a width of (c + 4) ft, so its area would be

feet. Using the distributive property, we can simplify this to:

So the area of this particular rectangle would be
3c + 12 sq. ft
1. 8^3 * 8^2, 8^5, and (2^3)^5
2. 6^9, and 6^5 x 6^4
