The sides of the triangle are 3x, 4x and 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5
first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm

18(12)=216
Because 1000 has 3 zeros, add 3 zeros after 216. Answer is 216,000
The answer is 2, simply because you need to make that negative sign a positive sign. To do that you will need to flip the numerator and denominator. Meaning that it will be 4/1 now. By doing this your exponent became positive! So if your teacher just wanted you just rewrite it, it would be (4/1)^1/2, but if you were to evaluate that, it would be 2
