Answer: 12v² + 18v

Step-by-step explanation:

Given

6v (2v + 3)

Apply distributive property by multiplying 6v to both 2v and 3

= 6v · 2v + 6v · 3

= 12v² + 18v

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{1}{3}[/tex] , then

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute (6, 3 ) into the partial equation

3 = - 2 + c ⇒ c = 3 + 2 = 5

y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line

The acceleration due to gravity on the surface of the Moon is about 1.625 m/s2. So, an object the mass of 10 kg. will weigh 10 × 1.625 = 16.25 N (newton) on the moon.

The mass will be 16.25 Kg

Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.

Gravity is the force with which the earth attracts a body towards its centre. Let us consider two bodies of masses ma and mb. Under the application of equal forces on two bodies, the force in terms of mass is given by:

mb = ma [aA/aB] this is called an inertial mass of a body.

Given:

mass of object = 10 kg

Acceleration due to gravity on Moon

=1.625 m/s²

So,

Mass of object on moon= 1.625 * 10 = 16.25 Kg

Answer:

Circle B has an area of 200.96 in².

Step-by-step explanation:

π = 3.14

radius of circle A = diameter of circle A/2

= 16 in/ 2 = 8 in.

Area = πr² = (3.14)(8²)

= (3.14)(64)

= 200.96 in²

Answer:

option A is the correct answer.

Answer:

[tex]p=-6.25[/tex] or [tex]p=\displaystyle-\frac{25}{4}[/tex]

Step-by-step explanation:

[tex]-160=22+8(3p-4)[/tex]

Our goal here is to isolate p on one side of the equation. We will do this by performing inverse operations on both sides.

Subtract 22 from both sides:

[tex]-160-22=22+8(3p-4)-22\\-182=8(3p-4)[/tex]

Divide both sides by 8:

[tex]-22.75=3p-4[/tex]

Add 4 to both sides:

[tex]-22.75+4=3p-4+4\\-18.75=3p[/tex]

Divide both sides by 3:

[tex]-6.25=p[/tex]

You can also convert this into a fraction:

[tex]p=\displaystyle-\frac{25}{4}[/tex]

Answer:

31 Minutes

Step-by-step explanation:

4.78 = 0.15 + 0.58

0.15m = 4.78 - 0.58

m = 4.78 - 0.58 divided by 0.15 = 28 minutes

So in total we have 28 + 3 = 31 minutes

Answer:

x=15

Step-by-step explanation:

3(x-5)=30

First, you would distribute the three to the x and the negative five.

3x-15=30

Then you would add 15 to the 15 to cancel it and to the 30 to make it even.

3x-15=30

  +15=+15=

3x=45

Finally, you would divide 3 into both sides, cancelling out the three and fiving you,

x=15

Hope this helped!

Start by distributing the 3 through the parenthses on the left side.

This gives us 3x - 15 = 30.

Now add 15 to both sides to end up with 3x = 45.

Dividing both sides by 3, we fin that x = 15.

Answer:

Mid point of A(9,2) and B(6,44) is (7.5, -1)

Step-by-step explanation:

I. If mid point = [tex]\frac{x_{a} +x_{b} }{2}[/tex], [tex]\frac{y_{a}+ y_{b} }{2}[/tex]

 So (x) = (9 + 6) / 2 = 7.5

       (y) = (2 + (-4)) / 2 = -1

So (x,y) = (7.5, -1)

Answer:

63

Step-by-step explanation:

Area = large rectangle + small rectangle + triangle

A = (L1 * W1) + (L2 * W2) + 1/2 base * heigth)

A = (9 * 5) + (2 * 3) + 1/2(((2 + 5 + 2) - (3)) * 4))

A = 45 + 6 + 1/2((9 - 3) * 4)

A = 51 + 1/2(6 * 4)

A = 51 + 1/2(24) = 51 + 12 = 63

Use the area of rectangle formula which is:

[tex] \displaystyle \large \tt{A = width \times length}[/tex]

Given that:

Substitute in the formula:

[tex] \displaystyle \large{16 = 8 \times (x - 5)} \\ \displaystyle \large{16 = 8(x - 5)}[/tex]

Distribute 8 in the expression:

[tex] \displaystyle \large{16 = (8 \times x) + (8 \times ( - 5))} \\ \displaystyle \large{16 = 8x - 40}[/tex]

Move -40 to another side and change from -40 to 40.

[tex] \displaystyle \large{16 + 40 = 8x} \\ \displaystyle \large{56= 8x} \\ [/tex]

Then move 8 to divide 56, leaving only x.

[tex] \displaystyle \large{ \frac{56}{8} = x} \\ \displaystyle \large{7 = x} \\ [/tex]

Hence, the answer is:

[tex] \displaystyle \large \boxed{x = 7} \\ [/tex]

Answer:

x = -1

Step-by-step explanation:

3x - (7x +12) = 2(x - 3)

3x - 7x - 12 = 2x - 6

-4x - 12 = 2x - 6

-12 = 6x - 6

-6 = 6x

x = -1

Check:

-1(3) - (-1(7) + 12) = 2(-1 - 3)

-3 - (-7 + 12) = -2 - 6

-3 - (5) = -2 - 6

-8 = -8
