Help anyone can help me do this question 2,I will mark brainlest.

see explanation

Step-by-step explanation:

For the triangle to be isosceles it must have 2 equal sides.

Calculate the length of the sides using the distance formula

d =

with (x₁, y₁ ) = A (- 1, 2) and (x₂, y₂ ) = B (3, 5)

AB =

     =

     =

     = = = 5

Repeat with (x₁, y₁ ) = A (- 1, 2) and (x₂, y₂ ) = C (3, - 1)

AC =

      =

      = = = 5

Consider B (3, 5) and C (3, - 1)

Since both x- coordinates are 3, this is a vertical line and its length is the difference of the y- coordinates, that is

BC = | - 1 - 5 | = | - 6 | = 6

Then

AB = AC = 5 , BC = 6

Since AB = AC = 5 then the triangle is isosceles

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
