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."
- Here, the number outside the bracket is 2.
- So, 2 is multiplied with each terms m and n 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,
- The number of grandstand ticket is g.
- The number of bleachers ticket is b.
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.
