The area of a rectangular wall of a barn is 55 square feet. It's length is 6 feet longer than the width. Find the length and width of the wall of the barn.

Answers

Answer 1

Answer: x - width
x+6 - length

$x(x+6)=55\n x^2+6x-55=0\n x^2+11x-5x-55=0\n x(x+11)-5(x+11)=0\n (x-5)(x+11)=0\n x=5 \vee x=-11$

x=5 feet
x+6=11 feet

Answer 2

Answer:

Final answer:

The dimensions of the barn wall are found by setting up and solving a quadratic equation involving its area and the relationship between its length and width. Discarding the nonsensical negative solution, we find that the width of the wall is 5 feet and the length is 11 feet.

Explanation:

Given that the area of the rectangular wall is 55 sq. ft. and the length is 6 ft. longer than the width, we can assign the width as x and the length as x + 6. Therefore, length multiplies width equals to the area of the rectangle, we then have the equation: x * (x + 6) = 55.

After rearranging the equation, we obtain: x² + 6x - 55 = 0. This is a quadratic equation that we can solve using the quadratic formula or by factoring if possible. Factoring results in (x - 5)(x + 11) = 0. Setting each factor equal to zero gives the possible solutions x = 5 and x = -11.

However, since the dimensions of a physical object (in this case, width of the barn wall) cannot be negative, we discard x = -11. Therefore, the barn wall has a width of 5 feet and a length of 5 + 6 = 11 feet.

What you do is that you use your algebraic magic to find your c value. First, you will divide both sides by 5. Now you have 2b= the square root of c +2. Now subtract 2 from both sides and you will have 2b-2= the square root of c. To undo the square root of c, you will need to square it, so square both sides and you have your answer. Good luck!

very easy
just add up all the meadals

japan is 38

so total=104+88+82+x+44+38=356+x
total of all medals is 421 so to find brittan or x you just subtrac the total from the big total so

356+x=421
subtract 356 from both sides
x=65
brittan won 65 medals

Total is 421,
United States (104)+ China (88)+ Russia (82)+ Germany (44)+ Japan (3*)
= 104 + 88 + 82 + 44 = 318 (idk wat japan # is)

so because ur photo is cut off u need to do *318 + japan's number* then do 421 minus *that number* that is what great Britain ( x ) is

so in the end x (great Britain) = 65

What is 3/7 reduce to its lowest term

Answers

3/7 Is already in the simplest term because there is no common factor between 3 and 7 unless it's a decimal, but we don't use decimals in fractions. So 3/7 simplified is just 3/7!

That is the lowest form of 3/7... you can not divide 3 by 7.. say the fraction was 2/4.. you would be able to take 2 divided by 4 and get 1/2.

The vertex is (4, -2) and the graph goes down.

Write the definition of a function absoluteValue, that receives an integer parameter and returns the absolute value of the parameter's value. So, if the parameter's value is 7 or 803 or 141 the function returns 7, 803 or 141 respectively. But if the parameter's value is -22 or -57, the function returns 22 or 57 (same magnitude but a positive instead of a negative). And if the parameter's value is 0, the function returns 0.

Answers

Answer:

Step-by-step explanation:

The value absolute is the function $|*|: \mathbb{R}\rightarrow \mathbb{R}^+$ defined by $|x|= x$ if $x$ is a positive number and $|x|=-x$ if $x$ is a negative number.
