Watch closely:
It's 7x
7-2x
35
Expressed as an algebraic expression, this would be equal to 7x - 5.
X+-7
What is the standard form for (2x+7)(x-1)=0
Product means the answer to a multiplication: 8 x 12 = 96 (Not sure what is meant by 'algebraic form' ?)
7-2x
35
3x
It is: 15x
It is two terms of an algebraic expression in the form of: x-15y
Expressed as an algebraic expression, this would be equal to 7x - 5.
X+-7
175 = 5 x 5 x 7 = 52 x 7
What is the standard form for (2x+7)(x-1)=0
The algebraic expression for "7 increased by x" is 7 + x. In this expression, the variable x represents the amount by which 7 is being increased. Adding x to 7 results in the total value after the increase.
