Can you help me with this question? I am trying to figure out the second one in the bracket, but if you would like to correct the other ones please do!

If f(x)=x^3 and g(x)=2x+7 when g(x)=-5

For the equations below which statement is true ? -2x=14 6x=-42

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
