Obviously, it's not rational, because it's the sum of two square roots, so cancel out A and B right away.
If we solve it
sqrt (18) + sqrt (2)
= sqrt (9*2) + sqrt (2)
= 3 sqrt (2) + sqrt (2)
= 4 sqrt (2)

<span>The cosine of pi/2 is 0 so the problem really says "find the angle between - pi/2 and pi/2 whose tan = 0. That would be the same as asking for the angle whose sin is 0. That would be 0.

Answer:
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
Step-by-step explanation:
Perimeter of a triangle = side a + side b + side c
Side a = (8.3f + 9.6g)
Side b = (3.6f + 1.5h)
Side c = (6.7h - 2.9g)
Perimeter of a triangle = side a + side b + side c
= (8.3f + 9.6g) + (3.6f + 1.5h) + (6.7h - 2.9g)
= 8.3f + 9.6g + 3.6f + 1.5h + 6.7h - 2.9g
Collect like terms
= 8.3f + 3.6f + 9.6g - 2.9g + 1.5h + 6.7h
= 11.9f + 6.7g + 8.2h
Perimeter of a triangle = (11.9f + 6.7g + 8.2h) cm
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
