3x*3x =9x^2
3x*-5=-15x
3x*-7=-21x
-7*-5=35
add your terms together in standard form
answer is C
Hey! :)
Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.4 : 5 ( = 9 too little )8 : 10 ( = 18 just right)12 : 15 ( = 27 too much)So per necklace, 8 yellow beads and 10 blue beads would be needed.
Hope this helps! :)

Correct answer: C. -20
Step-by-step explanation:
If (x-3) is a polynomial factor it means that the polynomial value at point 3 is zero.
H(3) = 3 · 3³ - 2 · 3² + 3k - 3 = 0 ⇒ 81 - 18 + 3k - 3 = 0 ⇒ 3k + 60 = 0
3k = - 60 ⇒ k = - 60/ 3 = - 20
k = - 20
God is with you!!!
