To find the like terms in the expression y + 1.2y + 1.2z, we need to identify terms that have the same variable(s) raised to the same power. In this case, the like terms are A) y and 1.2y. Both have the variable y raised to the power of 1.

To simplify 2 + 17x - 5x + 9, we combine the like terms by adding or subtracting their coefficients. The like terms here are 17x and -5x since they both have the variable x raised to the power of 1. So, the simplified form is B) 12x + 11.

To simplify 3(5y + 6) - 4, we need to apply the distributive property by multiplying 3 to each term inside the parentheses. This gives us 15y + 18 - 4. Further simplifying by combining like terms, the answer is A) 11y + 14.

To factor 81 - 27p, we need to find common factors in both terms. In this case, both terms are divisible by 27. Factoring out 27, we get 27(3 - p). So, the factored form is B) 27(3 - p).
