What is the simplest form

3/4 + 2/5

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

If eh = hg and hg=16, find the diameter of k

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 =
