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.
Let the number be x and so the expression is 8x

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.

Oh, dude, it's like super easy. So, if you have a number, let's call it "x," and you want to write "25 less than a number," you just subtract 25 from that number. So the algebraic expression would be x - 25. That's it, simple math, my friend.
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.
