un campo de futbol tiene 100m de largo y 60m de ancho¿ Cuales son la longitud y la anchura del campo?

Answer:

-4,-4

Step-by-step explanation:

let the numbers be x and y.

x+y=-8

y=-x-8

xy=16

x(-x-8)=16

-x²-8x=16

x²+8x+16=0

x²+4x+4x+16=0

x(x+4)+4(x+4)=0

(x+4)(x+4)=0

x=-4,-4

Answer:

Diagram B

Step-by-step explanation:

Diagram A makes sense to have a line of best fit because there is a common amount of data for where the next points probably will be. The points are close to the line of best fit, and there are pretty much an even amount of points on each side of the line. So, Diagram A’s line of best fit makes sense.

Diagram C makes sense to have a line of best fit because about the line, all the points are right next to it, and the line of best fit gives a nice representation of the data. So, Diagram C’s line of best fit makes sense.

For Diagram B, all of the points all scattered across the graph and none of them are close to the line of best fit, and a line a best fit is usually made to make an estimat of where the data will be, but for example, the point (20,90) is nowhere near the line of best fit. So, Diagram B’s line of best fit should not have been drawn.

Answer:

B- y=[tex]\frac{1}{4}[/tex]x-2

Step-by-step explanation:

To look at the slope you can count over four and then up one and its at the next point.

Also, the place on the y-axis is at -2

So, b makes the most since :)

Hope this helps :) (if it does, brainliest??)

Answer:

Volume= 360 feet³

Step-by-step explanation:

We have two shapes, a triangular prism and a rectangular prism.

Rectangular Prism: [tex]w=6, h=2, l=8, V=lwh[/tex]

So, the volume is 6×2×8=96 feet³

Triangular Prism: [tex]h=5.5-2=3.5, w=6, l=8, V=\frac{1}{2}lwh[/tex]

So, the volume is (5.5×6)÷2 ×8= 33×8=264 feet³

We have to combine the two volumes to find the volume of the whole shape. 96+264=360. So, the volume of the whole shape is 360 feet³

Answer:

x = 1

Step-by-step explanation:

First perform the indicated multiplication:  

3(2x+1)=4x+5 becomes 6x + 3 = 4x + 5.

Consolidate like terms:   2x = 2

Solve for x:  x = 1

Answer:

Step-by-step explanation:

To solve the equation, first you would multiply 3 times 2x and 3 times 1.  Then, you would write 6x plus 3 on the right side of the equation.  Then, you would subtract 3 from both sides of the equation.  You then will have 6x=4x+2.  Lastly, you would get an answer of x=1

Answer:

B and E

Step-by-step explanation:

-14 is the answer that is used to see if they are equal or not

A is incorrect because it equals -6.

B is correct because it equals -14.

C is incorrect because it equals 6.

D is incorrect because it equals -6.

E is correct because it equals -14.

x=1

Answer:

x = +√30

Step-by-step explanation:

Please write 30 = x squared as 30 = x^2.

If x^2 = 30, there are two solutions:  x = +√30 and x = -√30.

Several possible answers are given.    x=30−−√ is closest to the correct one, but must be written as x = √30.  Please ask someone how to find the "√" operator in Brainly.  Or, just write "sqrt(      )" instead.

Answer:

85 if the "2" in 10w(2) is being multiplied.

But if not, then

115 if the "2" in 10w2 is an exponent.

Answer:

85

Step-by-step explanation:

10(3)2 + 9(3)-2

(30)2 + (27)-2

60+25=85

Answer:

(3 - [tex]\sqrt{159}[/tex]) / 14 ≈ -0.7

(3 + [tex]\sqrt{159}[/tex]) / 14 ≈ 1.1

Step-by-step explanation:

this quadratic has no real roots because of the negative square root

Answer:

(x-3)(x-9)

Step-by-step explanation:

first thing you need to do is move the -6 over. so we're going to add 6 to both sides (we add because it's negative 6 and we need 0 on the right side)

so you have: x^2-12x+27

now we need to come up with two numbers that add to -12 and multiply to 27.

the factors of 27 are 9 & 3 and 27 & 1. only 9 & 3 add to 12 so we are going to use those.

since the 12 is negative however, 9 and 3 should both be negative.

therefore we get: (x-3)(x-9)

*it doesn't matter which order you put them in!
