-2(x + 5) = -16

= ???

x = 3

Step-by-step explanation:

Given

-2(x + 5) = -16

Expand the bracket

-2 x X +-2 x 5 = 16

The positive sign changes to minus

-2x - 10 = -16

Add 10 to both sides

-2x -10 + 10 = -16 + 10

-2x = -6

Divide both sides by-2

x = -6/-2

x = 3

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
