How do I factor out a constant before factoring out a quadratic? <br>Factor completely: 3w^2-3w-90
pantera1 [17]
3w^2-3w-90 =0 \ \ \:3 \\ \\w^2- w-30 =0 \\ \\a=1 , \ b= -1 , c= -30 \\ \\\Delta =b^2-4ac = (-1)^2 -4\cdot1\cdot (-30) =1+120=121 \\ \\w_{1}=\frac{-b-\sqrt{\Delta} }{2a}=\frac{1-\sqrt{121}}{2 }=\frac{ 1-11}{2}=\frac{-10}{2}=-5

w_{2}=\frac{-b+\sqrt{\Delta} }{2a}=\frac{1+\sqrt{121}}{2 }=\frac{ 1+11}{2}=\frac{12}{2}=6 \\ \\ Answer:\\ \\ w^2- w-30 =(x+5)(x-6)

Need some help, Thank you!!! ^^
stira [4]

Given:

3b+8\geq 14

To find:

The steps to solving the given inequality.

Solution:

We have,

3b+8\geq 14

Subtract 8 from both sides.

3b+8-8\geq 14-8

3b\geq 6

Divide both sides by 3.

\dfrac{3b}{3}\geq \dfrac{6}{3}

b\geq 2

Two steps are:

1. Subtract 8 from both sides of the inequality.

2. Divide both sides of the inequality by 3.

Therefore, the correct option is A.

MissTica

Answer:

0.2

Step-by-step explanation:

We have,

Number of blue tiles = 2

Number of red tiles = 3

Number of yellow tiles = 5

Total number of tiles = 2 + 3 + 5 is 10

Now, the probability of picking a blue tile is:

The number of blue tiles divided by the total number of tiles:

2 ÷ 10 = 0.2
