COMO PUEDO SOLUCIONAR EL SEGUNDO? 1-Encuentra A - B para los conjuntos a continuación:

B = {1, 2, 4, 6}

A = {1, 2, 4, 6, 7, 8, 9}

2-Encuentra B - A

A = {x / x es un número mayor que 6 y menor que 10}

B = {x / x es un número positivo menor que 15}

3-Encuentra B - A y A - B

A = {7, 8, 9}

B = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}

the square root of what number? if you add that, then someone will probably answer the question.

yes

step-by-step explanation:

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

******************

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
