That is an expression and this way it can only be factored. m^2 - 49 (m - 7)(m + 7) Wanting an answer implies an equation. m^2 - 49 = 0 m^2 = 49 m = +/- 7 same answer
Unfortunately, this website can't reproduce most mathematical symbols, so we have to guess. The value of 4m + 3 if m = 5 is 23

Well, honey, the algebraic expression for "3 more than m" is simply m + 3. It ain't rocket science, just add 3 to the variable m and you've got your answer. Math doesn't have to be complicated, sugar, just keep it simple and you'll be just fine.
Density is the mass per unit volume. By direct translation, ρ = m/v
