x2+7
The Base in the Algebraic Expression can be a Number or A Variable. EX. 42 or X2 - 4 and X are the base.
Oh, dude, it's like you're asking me to do math at a party. Okay, so "thrice a number" is just 3 times a number, and "five less than" means you subtract 5. So, the algebraic expression for "five less than thrice a number" would be 3x - 5. Easy peasy, right?
Let the number be x and so the expression is 8x
The algebraic expression for three more than a number is: X + 3
2x + 7
It is 2n + 20.
2x + 5
x2+7
Let the original number be y Therefore the new number is given by the expression 2y + 6
Double mean to multiply.For example: the algebra expression 2x can be written in the English Phrases like-Double a Number-Twice a number-Two of a number-Two times a number-or the product of two and a number.

To write "25 less than a number" as an algebraic expression, you would represent the unknown number as a variable, such as "x." Therefore, the algebraic expression would be written as "x - 25." This expression indicates that you are subtracting 25 from the unknown number represented by "x."
Suppose the function is "multiply a number x by two then subtract three and divide the whole thing by five". The algebraic expression would be: f(x) = (2x-3)/5
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
