How do you solve this A-4=

Answer:

-3x²+18x-27

Step-by-step explanation:

Given :

-3X²+18x

perfect square : (a+b)²=a² + 2ab + b²

[tex]\frac{-3x^{2} }{-3} +\frac{18x}{-3} ... something else[/tex] divide by -3 to have just a² type

x² -6x ...and something

compare with the perfect squere formula and we know a² is x² , a is x, so second term is 2xb and is -6x so b= -3

x²-6x+9 = (x-3)²

if you reverse and multiply by (-3) we have

-3x²+18x-27

The equation that is used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h, in pounds, of the hazelnut flavored coffee is c + h = 20 and 6c + 9h = 20(8)

An equation is an expression that shows the relationship between two or more variables and numbers.

Let c represent the amount of cinnamon flavored coffee, and h represent the amount in pounds, of the hazelnut flavored coffee.

The required blend is 20 pounds:

c + h = 20    (1)

Also:

6c + 9h = 20(8)  (2)

From eqn 1 and 2:

The equation that is used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h, in pounds, of the hazelnut flavored coffee is c + h = 20 and 6c + 9h = 20(8)

So, only B and D are trinomials.

Step-by-step explanation:

A trinomial is an algebraic expression having three terms in it.

A. 8x  

Not a trinomial because, it contains only one term.

B. 3y +5y2 + y

A trinomial because, it contains three terms.

C. 6x2

Not a trinomial because, it contains only one term.

D. x4 + x2 +1

A trinomial because, it contains three terms.

Answer:

The perimeter is equal to 240.

Step-by-step explanation:

Since  the shape is a regular polygon, the sides are equal to each other, so those two equations are equal to each other.

So, to solve for x, then to find perimeter, we need to set the equations equal to each other.

5x + 10 = 7x + 4

Subtract 5x  and -4 from both sides.

6 = 2x

Divide each side by 2.

3 = x

Now, we plug it into one of the equations and multiply by 6 (6 sides in the regular polygon).

5( 6 + 2 )

40

40 * 6 = 240

The perimeter is equal to 240.

Perimeter of the regular polygon is 150 unit

Given:

Equal first side of regular polygon = 7x + 4

Equal second side of regular polygon = 5(x + 2)

Find:

Perimeter of the regular polygon

Computation:

We know that side of regular polygon are equal

7x + 4 = 5(x + 2)

7x + 4 = 5x + 10

7x - 5x = 10 - 4

2x = 6

x = 3

So,

Side of regular polygon = 7x + 4

Side of regular polygon = 7(3) + 4

Side of regular polygon = 25 unit

We know that given polygon is hexagon

Perimeter of hexagon = 6(a)

Perimeter of hexagon = 6(25)

Perimeter of hexagon = 150 unit
