t(n) = (n+1)*(n+2)/2 where n = 1 ,2, 3, ...
10*abs(d - 3)
What does the algebraic expression x - 3 / 2 say in words
10
x + 3
i got 3 balls
10*abs(d - 3)
It is an algebraic expression.
Triangular numbers follow the form (n^2+n)/2
(3x+15)/2

The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.
It means whatever x is, multiply it by 3 and add 10
It would be: 3(7-d) as an algebraic expression
An algebraic expression that is not equal (Such as 3=0) is called an inequality, and can be expressed as 3≠0.
It is the same as: -2q-3 as an algebraic expression

The algebraic expression that represents fifteen less than the sum of ( y^3 ) and seven is ( (y^3 + 7) - 15 ). This simplifies to ( y^3 - 8 ).
