Answer:

Step-by-step explanation:

Factorize the denominator

Sum = 4

Product = 3

Factors = 1 , 3    {1*3 = 3 and  1+3 = 4}

x² + 4x + 3 = x² + x    + 3x + 1*3

                 = x(x + 1) + 3(x + 1)

                 = (x + 1)(x + 3)

GCF of the numerator and denominator = (x + 3)

Answer:

i think the answer is B . 22::2

According to the discriminant of the quadratic equation, it will have equal roots for p = -16.

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The discriminant is:

[tex]\Delta = b^2 - 4ac[/tex]

The solutions are as follows:

In this problem, the equation is:

[tex]f(x) = -x^2 + 8x + p[/tex]

Hence the coefficients are a = -1, b = 8, c = p.

It has equal roots if [tex]\Delta = 0[/tex], hence:

[tex]b^2 - 4ac = 0[/tex]

[tex]8^2 + 4p = 0[/tex]

[tex]4p = -64[/tex]

[tex]p = -16[/tex]

Answer:

13 times

Step-by-step explanation:

There are a total of 270 minutes in 4 1/2 hours.

270 ÷ 20 = 13.5

Though we know that 13.5 would not work out.

So she would check on it 13 times.

After the 13th time there will be 10 minutes left to cook the turkey.

The total number of times Alana will check the turkey before it sis done is 13 times.

The rate at which Alana is checking the turkey can be described as the work rate or the rate at which she is doing work.

The total number of times at which Alana will check the turkey before it is done is calculated as follows;

[tex]n = \frac{T}{R}[/tex]

where;

T is the total time = 4 1/2 h = (4 x 60) + 30 min = 270 min

R is the rate = 20 min

[tex]n = \frac{270}{20} \\\\n = 13.5 \ times\\\\n \approx 13 \ times[/tex]

There is no half checking, thus, the total number of times Alana will check the turkey before it sis done is 13 times.

Answer:

Ratios are like fractions. It is one part divided by the total amount of parts.

Step-by-step explanation:

for example there are 2 boys and 5 girls

so the ratio of boys to girls is 2:5

Step-by-step explanation:

you need either:

the diameter- the distance from one side to the other, or

the Radius- the distance from the center to the edge

the diameter is always double the radius, and accordingly the radius is always half the diameter.

so, the circumference ca be figured out by multiplying the diameter times pi- which, for most calculations is 3.14

if you only have the radius, multiply that by 2 to get the diameter, then by 3.14.

Answer: 23.

Step-by-step explanation:

Answer:

Equation of the line in point-slope form: y - 5 = -⅚(x - 2)

Equation of the line in slope-intercept form: y = -⅚x + 20/3

Step-by-step explanation:

Equation of a line can be expressed in the point-slope form as y - b = m(x - a), where,

m = slope = -⅚

a = 2

b = 5

Substitute the values into y - b = m(x - a):

y - 5 = -⅚(x - 2) => point-slope form.

We can rewrite this in the slope-intercept form, such as:

Multiply both sides by 6

6(y - 5) = -5(x - 2)

6y - 30 = -5x + 10

6y - 30 + 30 = -5x + 10 + 30

6y = -5x + 40

Divide both sides by 6

y = -5x/6 + 40/6

y = -⅚x + 20/3
