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
<span>–9x(5 – 2x)
= -45x + 18x^2
= 18x^2 - 45x
answer
</span>18x^2 - 45x
First you need to divide the area by pi. Then take that answer and square-root it. Your answer should come out to about 3.2 is the radius.
