a + 10
None of "these" expressions represent anything!
An equal sign (=) with a slash through (/) represents that two expressions are disproportional.
I am stuck on that one too sorry.

Write 2,784 in expanded notation as the sum of multiplication expressions
2(p+11)
The expression that represents two times the sum of p and 8 is 2(p + 8).
The result after adding a set of numbers or algebraic expressions is called the "sum." In mathematics, the sum represents the total value obtained from the addition of two or more quantities. For example, when you add 3 and 5, the sum is 8. Similarly, for algebraic expressions, the sum is the simplified expression resulting from the addition of the terms.
4(p+8) is one possibility.
The sum of multiplication expressions is the answer that you'd have, if you added together more than one multiplication expression. For example: 3 x 4 + 5 x 2 = A <--- A = the answer after you do/evaluate the expressions 12 + 10 = A 22 = A 22 is the sum of the above multiplication expressions (i.e. 3 x 4 plus 5 x 2)

The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.

37,594 in expanded notation as the sum of multiplication expressions is: (3 x 10000) + (7 x 1000) + (5 x 100) + (9 x 10) + (4 x 1)
One of the great things about arithmetic and addition is that, by definition, there is only one number that represents the sum of 0 and 10: and that is 10. There are not two such numbers.
Half the sum of 10 and a number can be expressed mathematically as ((10 + x) / 2), where (x) represents the unknown number. This formula captures the idea of first adding 10 to the number and then dividing the result by 2 to find half of that sum.
