2 squared is 4 3 cubed is 27 27 plus 4 is 31
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
Firstly divide 27 by 3.14 to get the diameter. Then divide that by two to get the radius. Then square that and multiply by 3.14 to get the area. You get the following mathematical expression: [(27/3.14)/2]^2∙3.14 Firstly divide 27 by 3.14 which is approximately 8.6. The expression is now: [8.6/2]^2∙3.14 Now divide 8.6 by 2 which equals 4.3. The expression is now: 4.3^2∙3.14 Then square 4.3 which equals 18.49. The expression is now: 18.49∙3.14 That equals 58.0586. Threfore the area is 58.0586 ft^2 if pi is rounded to 3.14.
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.
(60 - 2*27) + 9/3 = 9
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.
y = -26
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 ).
