Using the communative property of both addition and multiplication, 11+ab could be rewritten as ab+11, 11+ba or ba+11.
No. You need at least four.
6 x 53 = 6(50 + 3) = (6 x 50) + (6 x 3) = 300 + 18 = 318
Write the general algebraic expression for each using matchstick?
In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
It is: 4(x+y+z)
An expression equal to 15 + 35, using distributive property, is 5(3 + 7). Under distributive property, 5*3=15 and 5*7=35.
The answer depends on what the starting expression is. It is not easy to generate an equivalent expression for trigonometric functions, for example, without using an infinite series of exponents.
(21 x 2) + (25 x 2) = 46 x 2 = 92
The property used to rewrite 9x2 + 9x3 is the Distributive Property. Using the Distributive Property the expression can be rewritten as 9x2 + 9x2 + 9x2 or 27x2.
5 x 7
the distributive property is only used when simplifying expressions or solving an equation: to write an expression just translate the question into symbols and letters - you don't need to use the distributive property or any other property for that
In the most general sense, "simplify" means to replace an expression with an equivalent expression that is simpler. For example, 2x + 3x can be simplified as 5x (using the distributive property); x5x7 can be simplified as x12 (you may add exponents if the base is the same), etc.
