Answer:
x = 3
Step-by-step explanation:
Use FOIL method
(x - 5)(3x - 8) = x*3x + x*(-8) + (-5)*(3x) + (-5)*(-8)
= 3x² <u>- 8x - 15x</u> + 40 {Combine like terms}
= 3x² <u>- 23x</u> + 40
(4 - 3x)( 6 - x) = 4*6 + 4 *(-x) + (-3x)*6 + (-3x)*(-x)
= 24 <u>- 4x - 18x </u>+ 3x² {Combine like terms}
= 3x² <u>- 22x</u> + 24
(x - 5)(3x - 8) = (4 - 3x)( 6 - x) + 13
3x² - 23x + 40 = 3x² -22x + 24 + 13
3x² - 23x + 40 - 3x² + 22x - 24 - 13 = 0
<u>3x² - 3x²</u> - 23x + 22x + 40 - 24 - 13 = 0 {Combine like terms}
<u>0 </u> - x = 0
-x +3= 0
3 = x
x =3
I’m guessing red at this point-
25% chance of diamond
25% chance of club
V = 297 for a square pyramid, I hope its right..
