Asap! leah bought 4 pens and a bottle of nail color. her sister bought 2 of the same pens and 4 bottles of nail color, and spent the same amount as leah. the nail color cost $2. what is the cost of each pen? the equation 4x+2=2x+8 represents the problem.

Each pen is $3.00.

Step-by-step explanation:

4x+2=2x+8

(subtract 2 from both sides)

4x=2x+6

(subtract 2x from both sides)

2x=6

(divide 2 by both sides)

x=3

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

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,
