Find the area of the triangle I’ll send a picture of the triangle

The evaluated version of   ((x²-xy)-5x)-(4(2xy+2x²) is:

-x • (7x + 9y + 5)

Given, the expression is  ((x²-xy)-5x)-(4(2xy+2x²)

open the brackets.

x²-xy-5x-8xy-8x²

pull out the like terms.

-7x²-9xy-5x

= -x • (7x + 9y + 5)

Hence after evaluating ((x²-xy)-5x)-(4(2xy+2x²), we get -x • (7x + 9y + 5)

b) [tex]25x^{4} y^{3} z+5x^{7}y^{8} +10x^{2}y^{4} z\\[/tex]

Let us verify,

a)  Consider the trinomial   [tex]35x^{2} y^{5}z^{2} +5 x^{4}y^{9}z +15x^{3} y^{3}[/tex],

The Greatest Common Factor  of 35, 5, 15 is 5

The Greatest Common Factor  of  [tex]y^{5} ,y^{9} ,y^{3} = y^{3}[/tex]

There is no G.C.F for z because it is missing in the 3rd term.

So, the G.C.F  of the trinomial   [tex]35x^{2} y^{5}z^{2} +5 x^{4}y^{9}z +15x^{3} y^{3}[/tex] =  [tex]5x^{2} y^{3}[/tex]

b) Consider the trinomial   [tex]25x^{4} y^{3} z+5x^{7}y^{8} +10x^{2}y^{4} z\\[/tex],

The Greatest Common Factor  of 25, 5, 10 is 5

The Greatest Common Factor  of [tex]x^{4} ,x^{7} ,x^{2} =x^{2}[/tex]

The Greatest Common Factor  of [tex]y^{3} ,y^{8} ,y^{4} = y^{3}[/tex]

There is no G.C.F for z because it is missing in the 2nd term.

So, the G.C.F of the trinomial  [tex]25x^{4} y^{3} z+5x^{7}y^{8} +10x^{2}y^{4} z = 5x^{2} y^{3}[/tex]

Cost of 1 slice of pizza and 3 sodas = $5.25

When the requirements of a mathematical model are represented by linear relationships, the best result can be obtained using a technique known as linear programming (LP), also known as linear optimization. A particular type of mathematical programming is linear programming. Formally speaking, linear programming is a method for optimising a linear objective function under the constraints of linear equality as well as linear inequality. Convex polytopes, a set defined as that of the intersection of a finite number of half spaces, which are defined by a linear inequality, make up its feasible region. A real-valued affine (linear) function defined on the this polyhedron serves as its objective function. If there is a point in the polytope in which this function does have the smallest (or largest) value, a linear programming algorithm locates it.

Let the cost of 1 slice of pizza be x and cost of 1 soda be y.

Now,

Richard bought 3 slices of pizza and 2 sodas for $8.75

Therefore, [tex]3x+2y=8.75[/tex]

Jordan bought 2 slices of pizza and 4 sodas for $8.50

Therefore, [tex]2x+4y=8.50[/tex]

Solving above equations, we get         [tex]x=2.25[/tex] and [tex]y= 1[/tex].

Cost of 1 slice of pizza and 3 sodas = 2.25 + 3*1

                                                           = 2.25 +  3

                                                            = 5.25

Hence, Cost of 1 slice of pizza and 3 sodas = $5.25

Step-by-step explanation:

Midpoint between two points

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]

Given:

Substitute the given values into the formula:

[tex]\implies (6, 0)=\left(\dfrac{k-3+3h+4}{2},\dfrac{k-2+1-2h}{2}\right)[/tex]

[tex]\implies (6, 0)=\left(\dfrac{k+3h+1}{2},\dfrac{k-2h-1}{2}\right)[/tex]

Equating the x-values to create an expression for k:

[tex]\implies \dfrac{k+3h+1}{2}=6[/tex]

[tex]\implies k+3h+1=12[/tex]

[tex]\implies k+3h=11[/tex]

[tex]\implies k=11-3h[/tex]

Equating the y-values to create an expression for k:

[tex]\implies \dfrac{k-2h-1}{2}=0[/tex]

[tex]\implies k-2h-1=0[/tex]

[tex]\implies k-2h=1[/tex]

[tex]\implies k=2h+1[/tex]

Equate the expressions for k and solve for h:

[tex]\implies 2h+1=11-3h[/tex]

[tex]\implies 5h=10[/tex]

[tex]\implies h=2[/tex]

Substitute the found value of h into one of the equations for k and solve for k:

[tex]\implies k=2(2)+1[/tex]

[tex]\implies k=4+1[/tex]

To first start our problem, we will draw some coordinate axis at point E, since we are rotating the figure around this vertex. We get something like this

We are going to fix the point E. But we are going to rotate the figure in the direction in which the arrow shows. Since it is a 90° rotation, our goal is to align the blue vertical line, with the red horizontal line, following the direction of the black arrow. The picture would look like this

Note that the lengths of the new figure should remaing the same. That is, the side H' E should have a length of 3 squares and the length of H' G' should be 2 squares.

Answer:

if the question specifically says people then the amount of children are 54.

if the question specifically says the amount of adults in the park compared to the children when there are 216 adults, then the answer is 72.

Step-by-step explanation:

children and adults

so we know that this is a scale factor question because there is a ratio involved . the ratio is 9 to 3 . so the next ratio answer is 216 to what ?

how do you get from 9 to 216 ? the answer is that you multiply by 216 / 9 . this is a form of math short hand if you did not know already . to get from y to x, you multiply y by x/y.

so basically that means that you multiply 9 by 216 / 9 to get to 216 . that means that the scale factor is 216 / 9 . so you will want to multiply three by 216 / 9 because 216 / 9 is the scale factor .

216 / 9 is equal to 24 . now multiplying the scale factor by 3 is equal to 72 . therefore there are 72 children compared to 216 adults.

_____

children and people

if the question is asking specifically people not adults then instead you will want to add nine with three to get the total amount of people . 9 + 3 = 12 so the new ratio will be 12 people to three children . so with the same idea in mind 12 to 3 and 216 to what? to get from 12 to 216 you need to multiply by 216 / 12 thus 216 / 12 is the scale factor in this situation. 216 / 12 = 18 so the scale factor here is 18 so you need to multiply 18 by 3 to get the total amount of children there compared to the total amount of people . the total amount of children there are 54 .

Answer:

The angle 6 has its measure to be 80 degrees

The figure represents the given parameter

Also from the question, we have the following parameters that can be used in our computation:

m∠angle 7 = 100 degrees

The angles 7 and 6 are angles on the same straight line

As a general rule of angles, angles on the same straight line add up to 180 degrees

This means that

m∠angle 7 + m∠angle 6 = 180

Substitute the known values in the above equation

So, we have the following equation

100 + m∠angle 6 = 180

Subtract 100 from both sides

So, we have the following equation

- 100 + 100 + m∠angle 6 = 180 - 100

Evaluate the like terms in the above equation

m∠angle 6 = 180 - 100

Evaluate the like terms in the above equation

m∠angle 6 = 80

Hence, the measure of angle 6 is 80 degrees
