Part 1. create two radical equations: one that has an extraneous solution, and one that does not have an extraneous solution. use the equation below as a model:
a√x+b+c=d
use a constant in place of each variable a, b, c, and d. you can use positive and negative constants in your equation.
part 2. show your work in solving the equation. include the work to check your solution and show that your solution is extraneous.

part 3. explain why the first equation has an extraneous solution and the second does not.

Write an expression that has three terms and simplifies to 4x - 7. identify the coefficient(s) and constant(s) in your expression

The table represents a function. what is f(-2)? a.-3 b. -1 c.1 d.3

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
