Answer:

12x+6

Step-by-step explanation:

[tex](4x+2)3[/tex]

Use the distributive property to multiply (4x+2) by 3:-

[tex]12x+6[/tex]

Check the picture below.

so the quadrilateral is really just a parallelogram below a triangle, so let's simply get the area of each and sum them up.

The x-intercept of the graphed function is (-1,0)

The x-intercept of the graphed function is the point where the function has a value of 0

i.e. the x value when y = 0

From the complete question, we have:

x = -1 when y = 0

Hence, the x-intercept of the graphed function is (-1,0)

The area of the circle is the amount of space it occupies, and the area of the circle is 156.25π

The circumference, C is given as:

C = 25π

Start by calculating the radius using:

C = 2πr

So, we have:

2πr = 25π

Solve for r

r = 12.5

The area is then calculated using:

A = πr²

So, we have:

A = π * 12.5²

Evaluate

A = 156.25π

Hence, the area of the circle is 156.25π

Answer:

- for the number line check out the attached photo

- 7

Step-by-step explanation:

- on the number line, each small mark represents 1/6 so to make it easier I made the fraction into 1/6 form

- a coefficent is a numerical value placed before and multiplying the variable in an algebraic expression (ex. 4x)

In this case 7 is before the m making 7 the coefficent

Step-by-step explanation:

2 2/9? maybe because 1/8 is 6 times bigger than 1/2, so if you add 6 to 2 2/3 it would be 2 2/9?

You would need 1/4 white paint to mix with 2 2/3 quarts of blue paint to make the same shade of paint.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

The amounts of each type of paint as fractions of the total amount of paint: 1/2 quart of blue paint is 1/(1+1/2) = 2/4 = 1/2 of the total amount of paint, and 1/8 quart of white paint is 1/(1+1/2+1/8) = 1/8 of the total amount of paint.

So the ratio of blue paint to white paint in the original mixture is 1/2 to 1/8, or 4 to 1. To make the same shade of paint with 2 2/3 quarts of blue paint, we need to use the same ratio of blue paint to white paint.

So we need 1/4 as much white paint as blue paint, which is (1/4) × 2 2/3 quarts = 2/3 quart of white paint.

The error in the original solution was not correctly finding the ratio of blue paint to white paint in the original mixture, which is necessary to determine the correct amount of white paint to mix with a different amount of blue paint to create the same shade.

The equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) is

The Correct option is (C) and (E)

A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form ax+ b = 0.

The given equation is:− 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) .

= -3x+18 + 12 x -8x-3

=x +15

The corresponding equation to the above equation is:

C. x+15

D. (12 x - 11x) + (3-18)

= x-15

E. (12 x - 11x) + (18-3)

= x+15

F. (12 x - 11x) + (-6+3)

= x-3

As from the above it can be seen that the equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) . is

Vertex form of a parabola:  [tex]y=a(x-h)^2+k[/tex]

(where (h, k) is the vertex and [tex]a[/tex] is some constant)

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-(-1))^2-4\\y & =a(x+1)^2-4\end{aligned}[/tex]

Substitute the point (1, 0) into the formula:

[tex]\begin{aligned}\implies a(1+1)^2-4&=0\\4a-4&=0\\4a &=4\\a &=1\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=(x+1)^2-4[/tex]

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-4)^2+(-2)\\y & =a(x-4)^2-2\end{aligned}[/tex]

Substitute the point (6, 6) into the formula:

[tex]\begin{aligned}\implies a(6-4)^2-2&=6\\4a-2 & =6\\4a &=8\\a &=2\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:
