Answer:

$-x^3+x^2+x-6=0$

Step-by-step explanation:

Algebra

The equation is shown without proper format, we'll assume the correct equation is like

$\displaystyle 1-\frac{2}{x-2}=x+\frac{1}{x+2}$

Multiplying all the equation by (x-2)(x+2)

$(x-2)(x+2)-2(x+2)=x(x-2)(x+2)+(x-2)$

Operating

$x^2-4-2x-4=x^3-4x+x-2$

Rearranging and simplifying

$\boxed{-x^3+x^2+x-6=0}$

Tyler has a rectangular garden that measures 10 m wide by 13 m long. He wants to increase the area to 208 m² by increasing the w

Nikitich [7]

Rectangular garden:
length: 13 meters ; width: 10 meters

Area = 13 m x 10 m = 130 m²

Increase area to 208 m²

Find factors of 208 that is greater than 13.
208 / 13 = 16

Length: 13 + 3 = 16
Width: 10 + 3 = 13

The new rectangular garden will have a length of 16 meters and a width of 13 meters.

The weight of an object on Mars m is 40% of its weight on Earth w. Write a function rule for the situation. Then find the weight

Marrrta [24]

Answer: The weight of space probe on Mars is 6 lb.

Write a function rule for each situation. Then use your function as indicated. The force of gravity is less on Mars than it is on Earth. As a result, the weight of an object on Mars m is 40% of its weight on Earth w. Use your function to find the weight on Mars of a space probe that weighs 15 lb on Earth.

m is weight on Mars

w is weight on Earth

m is 40% of w

f(w) = m = (40/100)w

The weight of space probe is 15 lb on Earth

substituting w = 15 in the function we get,

f(15) = m = (40/100)15

= 6

ANSWER: The weight of space probe on Mars is 6 lb.

Step-by-step explanation:

Answer:

Hence, the answer is 40 pounds.

Step-by-step explanation:

An object that weighs 50 pounds on mars weighs 150 pounds on earth.

Let the object weighing 120 pounds on Earth, weighs x pounds on Mars.

We can solve this equation as :

x = 40 pounds

Hence, the answer is 40 pounds.

Or we can also solve this as :

150 pounds on Earth weighs 50 pounds on Mars.

1 pound weighs = pounds on Mars

And 120 pounds will weigh = pounds on Mars.

Think of a real-life situation, different from the situations already described in this activity, where knowing the percent

Illusion [34]

Answer:

Suppose the next case.

You want to buy an object from another state or country, you know that the cost of this object is C, and for bringing it from another place, you need to pay a tax, such that you do not know the exact value of the tax, you know that this can be between 3% and 9%.

Then the tax can be written as:

6% ± 3%

then the error is 3%, this means that the percent error is:

(3%/6%)*100% = 50%

Then you know that there is an error of 50% in the tax.

This can be helpful so you can estimate the maximum and minimum cost of tax that you will pay for this purchase.

Also there are a lot of situations where the percent error give us a lot of information.

"a measure of 10 cm with an error of 1 cm"

The percent error is: (1cm/10cm)*100% = 10%

And in a measure of 3cm with an error of 1cm we have:

(1cm/3cm) = 33.33%

In both cases we have the came error, but different percent error.

Then the percent error also tell us how much the error affects our measure.

Helpppp! pls! 10 points

iren2701 [21]

The product of the lengths of the parts of the chord is equal to the product of the lengths of the parts of the chord that divides it.

(7 cm)*(8 cm) = n*(4 cm)
(7*8 cm²)/(4 cm) = n
14 cm = n

$n=\boxed{14}cm$
