Answer:
<u>6b - 4a + 22 units</u>
Step-by-step explanation:
Perimeter = 2(length + width)
= 2(3b - 4a + 5 + 6 + 2a)
= 2(3b - 2a + 11)
= <u>6b - 4a + 22 units</u>
That's true; the Law of Cosines works with all triangles. With right triangles it simplifies to the Pythagorean Theorem.
Answer:
4/420=105
Step-by-step explanation:
