Answer:

x = 1

Step-by-step explanation:

Given

8x - 2(x - 7) = 20 ← distribute parenthesis on left side

8x - 2x + 14 = 20, that is

6x + 14 = 20 ( subtract 14 from both sides )

6x = 6 ( divide both sides by 6 )

x = 1

Six tools are in a bag – a hammer, wrench, drill, pliers, screwdriver, and measuring tape. You are trying to find the probabilit

Vesna [10]

You could roll a 6-sided die 3 times to simulate this. This is a good simulation because it has one side for each possible tool, and each roll is independent, just as selecting the tool with replacement would be.

Does someone know the answer to 3/12=2/?

Elina [12.6K]

Answer:

2/8

Step-by-step explanation:

since 3/12 = 1/4, you have to find a fraction that equals 1/4 that has 2 as the numerator.

that would be 2/8 since 1/4=2/8.

What is the common ratio for the geometric sequence? 18,12,8,163,… Enter your answer in the box.

uysha [10]

Answer:

$\frac{2}{3}$ .

Step-by-step explanation:

We have been given a geometric sequence 18,12,8,16/3,.. We are asked to find the common ratio of given geometric sequence.

We can find common ratio of geometric sequence by dividing any number by its previous number in the sequence.

$\text{Common ratio of geometric sequence}=\frac{a_2}{a_1}$

Let us use two consecutive numbers of our sequence in above formula.

$a_2$ will be 12 and $a_1$ will be 18 for our given sequence.

$\text{Common ratio of geometric sequence}=\frac{12}{18}$

Dividing our numerator and denominator by 6 we will get,

$\text{Common ratio of geometric sequence}=\frac{2}{3}$

Let us use numbers 8 and 16/3 in above formula.

$\text{Common ratio of geometric sequence}=\frac{\frac{16}{3}}{8}$

$\text{Common ratio of geometric sequence}=\frac{16}{3*8}$

$\text{Common ratio of geometric sequence}=\frac{2}{3}$

Therefore, we get $\frac{2}{3}$ as common ratio of our given geometric sequence.

Create a polynomial function in standard form with a leading coefficient of 2 and zeros at 0 1 and 3 brainly

TEA [102]

Answer:

$P(x) = 2x^3 - 8x^2 + 6x$

Step-by-step explanation:

Given

$p =2$ -- Leading coefficient

$Zeros: 0, 1\ and\ 3$

Required

Determine the polynomial

Represent the zeros with a, b and c.

Such that

$a = 0$

$b = 1$

$c = 3$

The polynomial is:

$P(x) = p * (x - a) * (x - b) * (x - c)$

$P(x) = 2 * (x - 0) * (x - 1) * (x - 3)$

$P(x) = 2x * (x - 1) * (x - 3)$

Open bracket

$P(x) = (2x^2 - 2x) * (x - 3)$

$P(x) = 2x^3 - 6x^2 - 2x^2 + 6x$

$P(x) = 2x^3 - 8x^2 + 6x$
