What does “x” stand for

In mathematics, it's a variable.

Step-by-step explanation:

In mathematics, it's a variable that could stand for a number. It's normally used in Pre-Algebra and up.

For example, if you say 5 + x = 15, you solve for x:

15 - 5 = x

10 = x

So plug the number in: 5 + 10 = 15.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√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,
