Answer:

A. 5

Step-by-step explanation:

use pythagorean theorem: a^2 + b^2 = c^2

but since we are finding the value of A; we'll use a= (square root) c^2 - b^2

A= 13^2- 12^2

A= 169 - 144

A= 25

A= 5 ( because we square root 25)

How many solutions does the equation -4x + 6 = 6x -2 have

SpyIntel [72]

Answer:

One.

Step-by-step explanation:

-4x + 6 = 6x - 2

-4x - 6x = -2 - 6

-10x = -8

There's only value of x which, when multiplied by -10 would produce -8.

That value is 0.8.

-10 * 0.8 = -8

No other value can produce the same result.

This means that there's only one solution.
