The expansion of the given expression is 7x + 7
Algebra is the branch of mathematics that aids in the representation of problems or situations in the form of mathematical expressions. In algebra, we use numbers with definite or fixed values such as 4, 9, 0.02, and so on. In algebra, we use variables such as x, y, and z in addition to numbers.
Given expression is 3(x+5)+4(x-2)
Now we have to expand and simplify the given expression
3(x+5)+4(x-2)
= 3x + 15 + 4x – 8
= 7x + 7
Therefore the expansion of the given expression is 7x + 7
