(x^2-14x+49)
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.
-7
7
If by 'x' you mean multiplied by, then the answer is yes. anything x 7 = 7 x that same number.
(x + 7)(x - 5)
4(7-1)
2(x - 7) = 8
x/7
It can be: x-7
3(y+7)
7.0 × 10-7
9X + 7
2(n+7)
abs(2n - 7) = 3n/2 abs(2n - 7) may also be written as |2n - 7|
8.0e-7 or 8.0 x 10-7
x = 22
It is 9*(n + 7)
