A and D and E
Step-by-step explanation:
Substitute the variable(in this case) t for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable t for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent
Hope this helps :)

Step-by-step explanation:
Given expressions:
3(2t + 5) and 6t + 153(2t + 5) = 3(2t) + 3(5) = 6t + 15, the expressions are equivalentThe value of both expressions when t=3 is 33.
6*3 + 15 = 18 + 15 = 33CorrectThe value of both expressions when t=3 is 23.
IncorrectThe value of both expressions when t=6 is 41.
6*6 + 15 = 36 + 15 = 51IncorrectThe value of both expressions when t=6 is 51.
CorrectThe two expressions are equivalent.
CorrectThe two expressions are not equivalent.
IncorrectОтвет:
6.x - 8^2 or x-64.
