What is the value of x?
pls help ;-;

Answer:

(4w^2+180w+1800) meters^2

Explanation:

(60+2w) x (30+2w)

1800+120w+4w^2+60w

Combine like terms and rearrange into quadratic equation

4w^2+180w+1800

Don't forget to put your units and since we are talking about area be sure to add your squared symbol

Answer:

C

Step-by-step explanation:

I chose C because it more detailed than the rest of the question. Everyone already knows how many months are in a year. What is for lunch today is just a normal question. How many students have a cell phone was not really detailed but it would have been different if they said "How many percentage of college students in math class uses cell phones.

Answer:

the required equation is y - 2/5x = 11/5

After graphing  x⁵ – 4x³ + x² + 2, we have

x-intercepts : x ≈ 2.16, x = 1, x ≈ 1.75

local maximums : (-1.63, 10.47)

local minimums : (1.46, -1.68)

increasing : 1.46 < x < -1.63

decreasing : -1.63 < x < 1.46

In discrete mathematics, and mοre specifically in graph theοry, a graph is a structure amοunting tο a set οf οbjects in which sοme pairs οf the οbjects are in sοme sense "related". The οbjects cοrrespοnd tο mathematical abstractiοns called vertices (alsο called nοdes οr pοints) and each οf the related pairs οf vertices is called an edge (alsο called link οr line).

Typically, a graph is depicted in diagrammatic fοrm as a set οf dοts οr circles fοr the vertices, jοined by lines οr curves fοr the edges. Graphs are οne οf the οbjects οf study in discrete mathematics.

Answer:

the answer is A 6 apples

Step-by-step explanation: you want to divide 38 by 8 if you do that you get 4 bags with 6 apples left

Answer: Carlos can fill 4 bags and have 6 left over

Step-by-step explanation:

The first step is to divide 38 by 8.

38 ÷ 8 = 4 with 6 left over.

That means that Carlos will be able to fill 4 bags and have 6 left over.

The answer is A, 6. Hope this helps, and good luck!

Answer: y=12 x =9

Step-by-step explanation:

In a parallelogram the diagonals bisect each other making them equal.

this means 2y + 6 = 30

we can rearrange this as 30 - 6 = 2y

24 = 2y  therefore y = 12

3x - 3 = 24

We can rearrange this as 24 + 3 = 3x

3x = 27

27 / 3 = 9

x = 9

Answer:

do you mean y=x-4-7 cause I can't understand that

Answer:

The first option

Step-by-step explanation:

Because when you multiply the first equation by 2, it sets the -x to -2x which helps cancel the variable out allowing you to easily solve the system of equations.

Answer:

I believe its "the value of y is 21 more tha the value of x, equation is y= x+21"

Step-by-step explanation:

Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3

Step-by-step explanation:

Answer is 30

The system has an infinite number of solutions because the equations have the same slope and y-intercept, and the graph of the equations is the same line.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The system of equations is given in the question, as follows:

-3x + 3y = 12

y = x + 4

When all the given equations are drawn in the graph, then we get the Infinitely many solutions ordered pairs in the solution set of the given system.

Here, the graph of the equations is the same line because the equations have the same slope and the same y-intercept. The system has exactly Infinitely many solutions.

Therefore, the correct answer would be an option (D).
