Control plus Z (Ctrl + Z) is a keyboard shortcut commonly used to undo the last action or command in many software applications. This can be particularly useful in text editing, graphic design, and data entry programs, allowing users to quickly revert mistakes or changes. In some applications, multiple Ctrl + Z commands can be used to undo several previous actions in succession.
control+z = undo
It is 5x+y
(z + 15)(z + 3)
2z + 5 - xz
Ten z plus one, or ten z plus ten. That depends on where you had parentheses in the original expression: (10 * z) +1 = 10z + 110 * (z + 1) = 10z + 10
control+z = undo
Expand z plus 11 times z plus 11 = (z+11)(z+11) = z2 + 22z + 121.
True
It is 5x+y
(z + 15)(z + 3)
10
2z + 5 - xz
x + y + z = x + z + y is the commutative property of addition.
Z + or - i and z-1
2z
z2
Ten z plus one, or ten z plus ten. That depends on where you had parentheses in the original expression: (10 * z) +1 = 10z + 110 * (z + 1) = 10z + 10
