Using factorization, the missing factor is (a + 6) of the given quadratic equation  a² + 8a + 12 = 0.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

Given

The quadratic equation is a² + 8a + 12 = 0

The factor of the quadratic equation will be.

[tex]\begin{aligned}a^2 + 8a + 12 &=0 \\a^2 + 6a + 2a +12 &= 0\\(a+ 6)(a +2 ) &= 0\\\end{aligned}[/tex]

Thus, the missing factor is (a + 6).

Answer:

Step-by-step explanation:

The distance between her house and the school is 1800 meters.

We must use the relation:

distance = speed*time

Here we have:

We should rewrite the time into seconds, then we have:

15 minutes = 15*(60 seconds) = 900s

Then the distance is:

distance = (2m/s)*(900s) = 1800m

Hey ! there

Answer:

Step-by-step explanation:

In the question we're given that Salima takes 15 minutes from her house to reach her school on a bicycle and bicycle has speed of 2m/s .

And we are asked to calculate the distance between her house and the school .So for finding the distance we need to know the speed formula that is ,

[tex] \: \qquad \: \qquad \: \red{\underline{\red{\boxed{\frak{Speed = \frac{Distance}{Time}}}}}} [/tex]

So ,

[tex] \:\qquad \quad \underline{\boxed{ \frak{Distance = Speed \times Time} } }[/tex]✦

As it's given in the question that the speed of bicycle is 2 m/s and she takes 15 minutes to reach the school . So , for finding distance we must have to convert 15 minutes into seconds .

We know that ,

Therefore in 15 minutes we have ,

Now Solving : -

[tex] \longmapsto \: \qquad \: \sf{Distance =2 \times 900}[/tex]

By , multiplying 2 and 900 , We get :

[tex] \longmapsto \: \qquad \: \purple{\underline{\purple{\boxed{\frak{ {Distance = 1800 \: m}}}}}}[/tex]

Step-by-step explanation:

use a ruler and a "set square", a tool to make a neat 90° angle. See image.

Point R can be anywhere as long as it is not on PQ. PQ can be at any angle or any length. There are many, many ways to follow these directions. The idea maybe be to practice using the tools or the idea may be that for any segment and point not on the segment, there exists a way to drop a perpendicular from the point to the segment.

The area of a shape is the amount of space on the shape

The approximate area of the circle is 27.52 square units

The given parameters are:

Sectors = 16

Base = 1.17 units

Height = 2.94 units

The area of the triangle is:

[tex]A_1 = 0.5 * Base * Height[/tex]

So, we have:

[tex]A_1 = 0.5 * 1.17 * 2.94[/tex]

[tex]A_1 = 1.7199[/tex]

The approximate area of the circle is then calculated as:

[tex]A_2 = 16 * A_1[/tex]

This gives

[tex]A_2 = 16 * 1.7199[/tex]

[tex]A_2 = 27.52[/tex]

Hence, the approximate area of the circle is 27.52 square units

Answer:

27.52

Step-by-step explanation:

A = 1/2 bh

fill in the given information

A = 1/2 (1.17)(2.94)

multiply 1.17 and 2.94

A = 1/2 (3.4398)

Mutiply 3.4389 by 1/2 or divide 3.4398 by 2 (it is the same thing)

A = 1.7199

Now you have the area of one of the triangles, so you have to find the area of the whole circle or 16 triangles.

A = 1.7199 (16)

Mutpily

A = 27.5185

round to the nearest hunderth

A = 27.52
