It is: 5k-7
The expression (x+5)(x-7) = x^2 -2x -35
3(y+7)
It can be: 7-4x as an algebraic expression
(5 - x) - 7
(5 × 7) ÷ 5 = 7
It is: 5k-7
-38
The product of 7 and 5 = 35
12
It is 7*256.
5 + 4g - 7 is an expression, not an equation (or inequality). An expression cannot be solved.
5(a+b)-7
sqrt 175 = sqrt 25 x sqrt 7 = 5 x sqrt 7
The expression (x+5)(x-7) = x^2 -2x -35
It would be: 3(7-d) as an algebraic expression
One such expression is 5n
