Question

Help with steps plz !!!!!

Answer 1

8+2z

Explanation:

(4+z)2

(8+2z) You multiply 2 to both numbers

so, 8 + 2z

Answer 2

because 2 is outside of the parentheses, that means that 4 can be multiplied with the numbers IN the parentheses so it can be distributed

2 • 4 is 8
2 • z is 2z

this means that 8 + 2z would be the answer, I hope I helped! :)
