They are similar because the corresponding lengths are proportional, 4:6 to is the same as 2:3

Answer:
D = 42
A = 42
Step-by-step explanation:
If ABC = DEF
A = D
x + 21 = 2x
21 = 2x - x
21 = x
A = x + 21
(21) + 21 = 42
D = 2x
2(21) = 42
I'm 90% sure. I'm not fully sure though.
To solve the problem, we can first change the denominator into the same:
3 1/3 - 1 2/9
= 3 (1×3)/(3×3) - 1 2/9
= 3 3/9 - 1 2/9
We can then proceed to carry deduction:
3 3/9 - 1 2/9
= 2 1/9
Therefore the answer is 2 1/9.
H^2 = P^2 + B^2
a. 6^2 = 2^2 + 3^2
36 = 4 + 9
36 = 13
Therefore this is not a Pythagorean triple
b.5^2 = 4^2 + 3^2
25 = 16 + 9
25 = 25
Therefore this is a phythagorean triple
