Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate
(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify
2(2+sqrt(10)) , 2(2-sqrt(10) =x

Given the isosceles trapezoid EFGH and side length JL = 93 units. If the length of KN = (3x + 1) and MN = (5x - 4), what is the length of KM?
Answer:
KM=JL=93 units
or KM=KN + MN= 8x-3
Step-by-step explanation:
The value of length of KM can be equal to either JL or obtained by adding KN = (3x + 1) and MN = (5x - 4) depending on the diagram.
An isosceles trapezoid has non parallel sides congruent.
In the isosceles trapezoid the diagonals are also equal.
There is a pair of parallel lines in an isosceles trapezoid.
In the 1st figure trapezoid JL and KM are diagonals.
If we take the JM and KL to be the parallel lines then the opposite sides can be JK and LM
And N is the middle line or the mid segment.
In the figure 2
The value of length of KM is obtained by adding KN = (3x + 1) and MN = (5x - 4)
KM=KN + MN = (5x - 4) +(3x + 1)
KM=8x- 3

The answer is C
Explain:
Solve for x in the first equation.
Add 4y to both sides of the equation
3x=12+4y
12y-9x=36
Divide each term by 3 and simplify
X=4+4y/3
12y-9x=36
Replace all occurrences of x with 4+4y/3 in each equation.
-36=36
X=4+4y/3
Since -36=36 is not true, there is no solution

The area of a rectangle is 38.5 square inches. The base of the rectangle is 4 inches. What is the height of rectangle?
Pls help me on this one. PLSSS :(
Answer:
The answer is 9.625
Step-by-step explanation:
So what you have is the area and the base of the rectangle. To find the height, just divide 4 into 38.5
38.5 / 4 = 9.625
To double check just multiple 9.625 by 4
9.625 x 4 = 38.5

Answer:
The price of one ticket is $76.
Step-by-step explanation:
5% of $330 is $16.50 and 45% of $330 is $148.50. Add those two together and then add $13 to it. You should get 178 and subtract it from 330 which leads you to 152. It asks for the price of one ticket, so you divide that by 2 which results to $76.
