4(21 + 4)
p = 4
x = 4
273 13+8 = 21 and 13*21 = 273
26 - 21 = 5 or 24 - 23 = 1
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
4(21 + 4)
7 + 21 + 2 + 86 + 4 = 120
It's 21.
p = 4
x = 4
273 13+8 = 21 and 13*21 = 273
26 - 21 = 5 or 24 - 23 = 1
2 squared is 4 3 cubed is 27 27 plus 4 is 31
-4 (-9 +5 = -4)
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
21, sigh.
