Imagine the paths as a right triangle with one leg measuring 8 miles and the other 5. You need to find the hypotenuse using the pythagorean theorem, so take 8 squared + 5 squared equals x squared, which gives you 64+25=89, then find the square root of 89 which is 9.433981132

1.6i+3/4d-3(1/2i-1.1d)-4.2
Scrat [10]

Answer:

4.05d+0.1i−4.2

Step-by-step explanation:

Let's simplify step-by-step.

1.6i+ 3/ 4 d−3( 1 /2 i−1.1d)−4.2

Distribute:

=1.6i+ 3/ 4 d+(−3)( 1/ 2 i)+(−3)(−1.1d)+−4.2

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

Combine Like Terms:

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

=( 3/ 4 d+3.3d)+(1.6i+ −3/ 2 i)+(−4.2)

=4.05d+0.1i+−4.2

Hope it helped!
