An expression of "4 less than b" can be represented as b - 4. This means you are subtracting 4 from the variable b. For example, if b is equal to 10, then 4 less than b would be 10 - 4, which equals 6.
if a is less than and not equal to b, it is written a < bIf a is less than or equal to b, it is written a ≤ b
The less than symbol looks like this: < This is where A < B ; A is less than B
This expression is an example of the Distributive Property. The expression a(b+c) = ab +ac is true because of the Distributive Property.
If the algebraic expression can be written in the form of a(x)/b(x) where a(x) and b(x) are polynomial functions of x and b(x) ≠0, then the expression is a rational algebraic expression.
9a4-b2=36a-2b=2(18-b) But if you meant 9a^4-b^2 it is not possible to factor
b-4 expression example b = 10 so b-4 = 6
b - 8
(b - 7) should do it.
-8<b<0
b - 15 = 28
The algebraic expression for "7 less than b" is b - 7. This means you are subtracting 7 from the variable b. In mathematical terms, subtraction is represented by the minus sign (-), so when you see "less than" in a mathematical context, it indicates subtraction.
5(a+b)-7
6x+4 is the expression that you are looking for.
b/12 - 11 = -5
9b2-7
4
(a+b)/2 - 10 a+b divided by 2 and then minus 10
