Are 3x and 4(x+1) -x -4 equivalent?

yes both of them are equal

Step-by-step explanation:

First simplify both sides of the equation:

3x is the most simplified it can be,

4(x+1)-x-4

Use distributive property  4(x+1)=4*x+4*1=4x+4  then   4x+4-x-4=3x

so therefore 3x=3x

YES

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
