Answer:
(4.2 units)
Step-by-step explanation:
By inspection of the illustration we can see that leg DE has length 3 and that leg DF also has length 3. By the Pythagorean Theorem, 3^2 + 3^2 = 2(3^2); thus, the length of the hypotenuse EF is 3√2, or approximately 4.24 units. The third answer choice (4.2 units) is the correct one.
3*squareroot(3) is the answer
2*sqrt(12) = 2*sqrt(4*3) = 2*sqrt(4)*sqrt(3) = 2*2*sqrt(3) = 4*sqrt(3)
sqrt(27) = sqrt(9*3) = sqrt(9)*sqrt(3) = 3*sqrt(3)
sqrt(48) = sqrt(16*3) = sqrt(16)*sqrt(3) = 4*sqrt(3)
therefore,
4*sqrt(3) + 3*sqrt(3) - 4*sqrt(3)
3*sqrt(3) + (4*sqrt(3)-4*sqrt(3))
3*sqrt(3)
