Multiply both sides by a
(a + 4)a = -3
Regroup terms
a(a + 4) = -3
Expand
a^2 + 4a = -3
Move all terms to one side
a^a + 4a + 3 = 0
Factor a^2 + 4a + 3
(a + 1)(a + 3) = 0
Solve for a
<u>a = -1, -3</u>
Answer: 12=7−3x+5x
Step 1: Simplify both sides of the equation.
12=7−3x+5x
12=7+−3x+5x
12=(−3x+5x)+(7)(Combine Like Terms)
12=2x+7
12=2x+7
Step 2: Flip the equation.
2x+7=12
Step 3: Subtract 7 from both sides.
2x+7−7=12−7
2x=5
Step 4: Divide both sides by 2.
2x

Step-by-step explanation:
The sample space is 120 , hence
Probability for picking a green marble is P(G) = 20/120 = 0.167
Probability for picking a blue marble is P(B)= 18/120 =0.150
Probability for picking a gray marble is P(Gr)= 20/120=0.167
Probability for picking an orange marble is P(O)=6/120=0.050
Probability for picking a yellow marble is P(Y)=4/120=0.033
Probability for picking a cat eye marble is P(Ce)=21/120=0.175
Probability for picking a multicolored marble is P(Mc) =31/120=0.258
