Answer: 9
Step-by-step explanation: You can start by setting this up as an equation, where X is Brooke’s age.
X + 2(x)+ 3 = 30
The 2(X) + 3 signifies the part of the problems identifying that Mia is twice her sisters age plus 3 years.
Combine x’s
3x + 3 = 30
Subtract 3 from both sides to isolate the x term
3x= 27
Divide both sides by 3 to reduce to a single x
X= 9 , which is brooke’s age
a regular polygon has all equal sides.
a PENTA=5, pentagon has 5 sides, so a regular pentagon has 5 equal sides.
