Answer:
The system has infinitely many solutions
Step-by-step explanation:
There are no variables left. And the final equation is correct.
It means the system is going to be correct for any value of variables. So there are infinitely many solutions
((3x^2)^a - (4y^a)(z^3a))^2
First, expand.
((3x^2)^a - (4y^a)(z^3a)) ((3x^2)^a - (4y^a)(z^3a))
Combine
3^(2a) - x^(4a) - 8 * 3^(2a)x^(2a)y^(a)z^(3a) + 16y^(3a)z^(6a)

Answer:
h =
Step-by-step explanation:
Given
bh + hr = 25 ← factor out h from each term on the left side
h(b + r) = 25 ← divide both sides by (b + r)
h =
