a + d
D + D = M
"the same as the others added together" For example: a=b+c+d a is equal to the sum of b plus c plus d. 9=2+3+4
4x2 -x -1 :D
6+6=12, easy :D
No; it is false. The sum of all the angles of a quadrilateral always equals 360o.
Expressed as a sum in hexadecimal form, F + D = 1C.
Omg I think I know! 73! Just kidding 75. :D
Unless the values of the things will no be know things, then the sum will also not be known
The verbal expression for "c plus 2d" can be stated as "the sum of c and twice d." This indicates that you take the value of c and add it to two times the value of d.
