Each term is equal the preceding term plus 3. Therefore the next term is 13 and the difference is +3.
Answer:
14
Step-by-step explanation:
12:6=2
12+2=14
so her brother it's 14 years old
If the diagonal is 32 than you will us
A^2 + b^2 = c^2
We will use the aspect ratio to find a common variable
4A = 3B
a = (3/4)B now plug it in
((3/4)B)^2 + b^2 = 32 (This is because c is the diagonal)
Now solve for B
B turns out to be 25.577 inches
Plug B in
A = (3/4)(25.577)
A = 19.18
Now add up ther perimeter A + A + B + B
19.18 + 19.18 + 25.577 + 25.577
89.6 inches
The prime factors are: 2 x 2 x 3 x 3
