Answer:

7.3

Step-by-step explanation:

In order to find the hypotenuse, we just need to use the Pythagorean Theorem.

Remember, that this theorem only works for right triangles.

This theorem states that a^2+b^2=c^2

This is where a and b are legs of the triange, and c is the hypotenuse.

Knowing this, we can plug our values in.

6.4^2+3.5^2=c^2

Simplify.

41.344+12.25=c^2

53.594=c^2

Root both sides.

c=7.32 (about)

Round that to tenths.

c=7.3

Ipatiy [6.2K]

9514 1404 393

Answer:

  x < -2  or  3 < x

Step-by-step explanation:

<u>6x -4 > 14</u>

  6x > 18 . . . . add 4

  x > 3 . . . . . . divide by 6

<u>3x +10 < 4</u>

  3x < -6 . . . . subtract 10

  x < -2 . . . . . divide by 3

The solution is the union of disjoint sets:

  x < -2  or  x > 3
