Hello friends how are you i dont know the answer ...
Can you explain what exactly you need to do because I know how to do this but I need more context
An expression means that you may not be able to find a final value, and that it is acceptable to have x in the answer.
The formula for the area of a triangle is A=1/2*b*h
A=1/2*(5x^2+4x)*(2x^2) (distribute the 1/2)
A=(5/2x^2+2x)(2x^2) (distribute the 2x^2)
A=5x^4+4x^3
Hope this helps
Ok so first u would add 3+1 which gives u 4 and then add 1/4 which should give u 4 1/4
