It’s
1. A
2 .B
3 .C
4 .B
Actually,
1A is correct
4A is a correct expression, but not completely factored
@idek is right THANK YOU SO MUCH!!!
1. To find the like terms in the expression y + 1.2y + 1.2z, you need to identify terms that have the same variables raised to the same powers. In this case, we have "y", "1.2y", and "1.2z".
The common variable here is "y". The terms "y" and "1.2y" both have "y" as the variable, so they are like terms. However, "1.2z" has a different variable ("z"), so it is not a like term.
Therefore, the correct answer is option A - "y and 1.2y".
2. To simplify the expression 2 + 17x - 5x + 9, you need to combine the like terms. Like terms in this case are terms that have the same variable, which is "x".
Start by combining the terms that have the variable "x". We have 17x and -5x. When we add these two terms, we get 17x - 5x = 12x.
Now add the remaining constant terms 2 and 9. 2 + 9 = 11.
Therefore, the simplified expression is 12x + 11. So, the correct answer is option B - "12x + 11".
3. To simplify the expression 3(5y + 6) - 4, you need to apply the distributive property. Multiply the coefficient "3" with each term inside the parentheses.
3(5y + 6) = 3 * 5y + 3 * 6 = 15y + 18
Now subtract 4 from this result: 15y + 18 - 4 = 15y + 14
Therefore, the simplified expression is 15y + 14. So, the correct answer is option C - "15y + 14".
4. To factor the expression 81 - 27p, you need to find common factors in both terms.
Both terms have a common factor of 27. Factor out 27 from both terms:
81 - 27p = 27(3) - 27p
Now, factor out the common factor of 27:
27(3 - p)
Therefore, the factored expression is 27(3 - p). So, the correct answer is option B - "27(3 - p)".
Wait not 4.A its 4.B
SE is wrong the answers are 1.A 2.D 3.C 4.A
More wild guesses.
