You can use the Grouping method to solve that polynomial
Answer:
x = - 4, x = 2
Step-by-step explanation:
Given
3x² + 6x - 24 = 0 ( divide through by 3 )
x² + 2x - 8 = 0 ← in standard form
(x + 4)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
Answer:
119 r 9
Step-by-step explanation:
Answer: see below
<u>Step-by-step explanation:</u>

3(x - 12) > 5(x - 24)
3x - 36 > 5x - 120
<u> -5x </u> <u>-5x </u>
-2x - 36 > -120
<u> +36</u> <u> +36 </u>
-2x > -84
<u> ÷ -2 </u> ↓ <u> ÷ -2 </u>
x < 42
Graph: ←------------o

34) 6[5y - (3y - 1)] ≥ 4(3y - 7)
6[5y - 3y + 1] ≥ 4(3y - 7)
6{2y + 1] ≥ 4(3y - 7)
12y + 6 ≥ 12y - 28
<u>-12y </u> <u>-12y </u>
6 ≥ -28
TRUE so the solution is All Real Numbers
Graph: ←-----------------------→
36) BC + AC > AB
4 + 8 - AB > AB
12 - AB > AB
<u> +AB </u> <u>+AB </u>
12 > 2AB
<u> ÷2 </u> <u>÷2 </u>
6 > AB
AB < 6

Check: let y = 16
then
(16 - 16) ≥ 16 + 2
0 ≥ 18
FALSE so the claim is wrong
40) question not provided in the image so I cannot give a solution.
-.5 + 2, you can think of this as 2 - .5 as well, it would equal out to be 1.5.
