Domain of 5x^2 + 2x - 1 is all real numbers.
The algebraic expression uses the terms to denote symbols
sum of means addition
difference of means subtraction
product of means multiplication
quotient of means division
Here we have the term 6x
which actually means 6 times x or
6 multiplied by x
hence by multiplication we use the word product of
so we have the product of 6 and a number as our right answer
-1/2 + 2 = 1.5
because if u add 2 to a minus half it goes 0 and then 1.5 (positive half)
Yeah the answer is number 5
31.+ addition
32. - subtraction
