2 answers:
Answer:
5
Step-by-step explanation:
The formula is 6x^2
If you set it equal to 150
Answer:
5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 = 25 + 25 + 25 + 25 + 25 + 25 = 50 + 50 + 50 = 150
5 would be the missing side because it fits the formula
(A x A) + (A x A) + (A x A) + (A x A) + (A x A) + (A x A) = Surface area

2⁻³² = (-2²)⁻⁶ • (2⁻⁵)⁻⁴
2⁻⁵ = (2²)² • (2³)⁻³
2⁸ = (-2⁻⁴)⁻² • (2²)⁰
1 = 2⁴ • (2²)⁻²
Can you please paste a picture of the triangle? I am happy to help, but I need to see the triangle. :-)
(2√5 + 3(√7))^2
(2√5 + 3(√7))(2√5 + 3(√7))
4*5 + 6√35 + 6√35 + 9*7
20 + 12√35 + 63
20 + 63 + 12√35
83 + 12√35
Keeping in mind that an hour is 60 minutes.
