Substitute 2 in for r, and you get 9 - 6 = 3.
Note: If this question is from work you have been assigned by a teacher or professor, I suggest you do the work yourself instead of trying to find the answers online. This will help you to better understand the material and become more familiar with it. Of course, if this question was not from homework, you can ignore this message.
It would help if the expression was given!
To determine the value expression when ( x = -2 ), you need to substitute -2 into the given expression. For example, if the expression is ( 2x + 3 ), substituting -2 gives ( 2(-2) + 3 = -4 + 3 = -1 ). The specific value will depend on the expression you have; please provide that for a more accurate answer.
Given a value of x, find the value for -3x + 2
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.

To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
To evaluate the expression when ( n ) equals a specific value, you substitute that value into the expression in place of ( n ). For example, if the expression is ( f(n) = n^2 + 3n ), you would calculate ( f(7) ) by substituting 7 for ( n ), resulting in ( 7^2 + 3(7) ). Similarly, for ( n = 0.4 ), you would substitute 0.4 into the expression and compute the result. This process allows you to find the numerical value of the expression for those specific values of ( n ).

5(5) is 25. 3(-2) is (-6). The expression becomes 25 - (-6). When subtracting a negative number, you actually "add the opposite," so the expression is now 25 + 6 (positive 6 is "the opposite" of -6); the value is 31.
The value of the expression (2^6) is calculated by multiplying 2 by itself six times: (2 \times 2 \times 2 \times 2 \times 2 \times 2). This equals 64. Therefore, (2^6 = 64).
2 squared is 4 3 cubed is 27 27 plus 4 is 31
