Answer:

y = (x+8)(x+3)

Step-by-step explanation:

The equivalent expression to the given quadratic equation is:

y = (x + 8)*(x + 3).

Here we start with:

[tex]y = x^2 + 11x + 24[/tex]

To solve the problem, we need to find the roots of the quadratic equation, to do it, we will use the Bhaskara's formula:

[tex]x = \frac{-11 \pm \sqrt{11^2 - 4*24} }{2} \\\\x = \frac{-11 \pm 5 }{2}[/tex]

Then the two solutions are:

Meaning that we can write the cuadratic equation as:

y = (x + 3)*(x + 8).

So the correct option is the first one.

Answer:

60

Step-by-step explanation:

Answer:

60°

Step-by-step explanation:

Suppose that Eldi has x years old now :

x + 4 = 3 × ( x - 10 )

x + 4 = 3x - 30

Add both sides 30

x + 4 + 30 = 3x - 30 + 30

x + 34 = 3x

Subtract both sides x

x - x + 34 = 3x - x

34 = 2x

2x = 34

Divide both sides by 2

2x ÷ 2 =34 ÷ 2

x = 17

_____________________________

Thus Eldi is 17 .

CHECK BY MULTIPLYING THEM.

Answer:

Answer C and D are correct.

Step-by-step explanation:

In c, 2m + m=3m, and then adding the 2 leaves you with 3m+2.

In d, m+m+m=3m, and then again you add the two.

Answer:

Let the number be x.

x doubled is 2x, and 2x is 20 greater than 200. So, we have this:

2x = 200 + 20

2x = 220

x = 110.

Answer:

The unknown number is 110.

Step-by-step explanation:

Let the unknown number be n.

Then your number, doubled, is 200 + 20 (20 greater than 200), so the pertinent equation is    2n = 200 + 20, or 2n = 220.

Then n = 110.

Check:  Is 2(110) = 200 + 20?  Is 2(110) = 220?  YES

Answer:

The Answer Is Five

Step-by-step explanation:

Because When You Take 20 From 112.50 Its 92.5 Then You Divide By 18.50 It Equals 5

A = 360 cm^2

Step-by-step explanation:

Using Pythagorean theorem, the length AB is given by

AB^2 = 17^2 - 8^2 = 225 cm^2

or

AB = 15 cm

Since the ratio BC: CD = 1:2 and BC = 8 cm, this means that CD = 2×(8 cm) = 16 cm

so the length BD is

BD = BC + CD = 8cm + 16 cm = 24 cm

There the area of the rectangle is

A = AB×BD

= 15cm×24cm

= 360 cm^2

C= 2pi r = 18 pi so

2r =18 so r = 18/2=9

Answer:

[tex]r=9[/tex]

Step-by-step explanation:

The equation to find the circumference of a circle when given the radius is the following,

[tex]C=r(\pi)(r)[/tex]

There (C) represents the circumference, (r) represents the radius, and ([tex]\pi[/tex]) represents the irrational numbers (3.1415...)

Substitute in the given values and backsolve for the radius,

[tex]18(\pi)=2(\pi)(r)[/tex]

Inverse operations,

[tex]18(\pi)=2(\pi)(r)[/tex]

[tex]9=r[/tex]

Answer:

x = 140

Step-by-step explanation:

The secants exterior angle theorem states that when two secants (lines that intersect a circle at two points) intersect each other outside of the circle, then the absolute value of the difference divided by (2) equals the angle formed by the intersection of the two secants. One can apply this theorem here by stating the following, call the measure of the unknown arc (y);

[tex]\frac{30-y}{2}=10[/tex]

Solve for (y) with inverse operations:

[tex]\frac{30-y}{2}=10\\\\30-y=20\\\\y = 10[/tex]

When there is a diameter in a circle, the degree measure of the arc surrounding the diameter is (180). One can apply this here by stating the following:

[tex]30 + x + 10 = 180[/tex]

Simplify,

[tex]40 + x = 180[/tex]

Inverse operations,

[tex]40+x=180\\\\x = 140[/tex]
