Lets Anna's age = A
Mr. Goldstein age = G
Mr. Goldstein is 4 times as old as his daughter Anna.
So G= 4A
In 4 years, he will be 3 times as old as Anna
we add 4 with Both their ages
G + 4 = three times of A + 4
G + 4= 3(A + 4)
We know G= 4A, replace it in above equation
4A + 4= 3(A + 4)
4A + 4= 3A + 12
Subtract 3A from both sides
A + 4 = 12
Subtract 4 from both sides
A = 8
So Anna's age = 8 years
Answer:
Yes totally friend, I totally hear you on that!! ^-^ Good luck for your weekend!!!
Step-by-step explanation:
AB=√{(6+3)²+(6-2)^2}=√(81+16)=√(97)
BC=√((7-6)²+(-1-6)²)=√(50)=5√2
AC=√((7+3)²+(-1-1)²)=2√(26)
Perimeter=AB+BC+AC=√97+5√2+2√(26)
