I need help with questions 4 and 5. Someone please help.

4) The option G) 2m + 2n is equivalent to the expression 2(m+n).

5) The option C) 25g + 15b represents the total cost.

Step-by-step explanation:

4) The given expression is 2(m+n).

To find the equivalent form of the given expression, the distributive property is used.

"The distributive property is defined as the distribution of the number outside the bracket to all the terms present inside the bracket."

⇒ 2(m+n) = 2m + 2n

The option G) 2m + 2n is equivalent to the expression 2(m+n).

5) The cost of grandstand ticket is $25 and the cost of bleachers ticket is $15.

It is given that,

To find the total cost :

Total cost = (cost× No. of grandstand ticket) + (cost× No. of bleachers ticket)

⇒ Total cost = 25g + 15b

The option C) 25g + 15b represents the total cost in dollars.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
