2(1,0) - 3(2,-1) = (-4,3)
3(1-1)-(4-2) = -2
42, because if there is nothing between the 7 and 'a' and 'a' equals 6 then the answer is 42.
It is some sort of an algebraic expression.
4-2 = 1/42 = 1/16 = 0.0625
The question contains only an expression. There is no property illustrated.
0.42
The expression for this type of problem is 6 + (42 / 21). Then, evaluate that by the order of operations to obtain: 6 + 2 = 8
X = 6 5x + 2x = 42
Okay, here is a postfix expression: 3 4 * 5 6 * + the evaluation: 3*4 + 5*6 12 + 30 42
42
It is an expression that can be simplified to: 4x2-42
43:42
The expression is 42/23
42 = 4*4 = 16
42, because if there is nothing between the 7 and 'a' and 'a' equals 6 then the answer is 42.
7x2+49x-42 = 7(x2+7x-6)
It is sin(42°)
