Answer:

Step-by-step explanation

subtract 8 from both sides

8-2x-8=-4x+4-8

simplify

-2x=-4x-4

add 4x to both sides

-2x+4x=-4x-4+4x

Simplify

2x=-4

divide both sides by 2

2x/2=4/2

simplify

x=-2

________

4=-6x     Then divide both sides by -6 that will give you your x value

Step-by-step explanation:

The Pythagorean triple (8, 15, 17) is often seen in algebra and geometry problems. You recognize it as choice A, so you know that is a right triangle.

__

A spreadsheet or graphing calculator can perform the tedium of comparing the sum of squares of the shorter sides to the square of the longer side. The attachment shows a spreadsheet used for that purpose. It identifies the triple (8, 15, 17) as the sides of a right triangle.
