PLEASE HELP
Zielflug [23.3K]

Answer:

  • x = 4
  • WX = WY = 25
  • XY = 17

Step-by-step explanation:

The triangle is isosceles with side WX equal to side WY:

  WX = WY

  9x -11 = 7x -3

  2x = 8 . . . . . add 11-7x

  x = 4

Then the side measures are ...

  WX = WY = 7(4) -3 = 28 -3 = 25

  XY = 4(4) +1 = 16 +1 = 17

PLEASE HELP ILL GIVE BRAINLIST <br><br> Write an equation in Standard Form that has roots -4 and 7.
Misha Larkins [42]

Answer:

x^{2} -3x-28

Step-by-step explanation:

To find this equation in standard form, first, write it in factored form. This looks like y=(x+4)(x-7). Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.

  1. Following the FOIL method, you should multiply the first terms in each binomial, x*x, which equals x^{2}.
  2. Then, the outside terms, x*-7. This equals -7x.
  3. Next, the inside terms, 4*x=4x.
  4. Finally, the last terms, 4*-7, this equals -28.

Then, add all of the terms together x^{2} + -7x+4x+-28. To get the standard form, combine like terms, this comes out to x^{2} -3x-28.
