Add. \( (6 z+2)+(2 z+6) \) Submit

Let’s combine those fun terms! Start with the \( z \)s: \( 6z + 2z = 8z \). Now for the constants: \( 2 + 6 = 8 \). So, when we put it all together, you get \( 8z + 8 \). Simplifying it a bit more, that can be factored out to \( 8(z + 1) \). Voilà! Looking to impress your friends with algebra? Try substituting actual numbers for \( z \). For instance, if \( z = 2 \), then \( 8(z+1) \) becomes \( 8(2+1) = 8 \times 3 = 24 \). It's a super fun way to see how the math functions and practice your skills!
