Answer:
$96
Step-by-step explanation:
120 x .20 = 24
120 -24 =$96
Answer: 20.5
Step-by-step explanation:
From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangle. 9-40-41 is a Pythagorean triplet.
In a right angled triangle, the circumradius is half the hypotenuse.
In the given triangle, the hypotenuse = 41.
Therefore, the circumradius is 41÷2= 20.5 units.
Answer: Choice B
=====================================
Explanation:
The given matrix is
![\left[\begin{array}{cc|c}1&5&11\\4&-6&-3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%265%2611%5C%5C4%26-6%26-3%5Cend%7Barray%7D%5Cright%5D)
The numbers to the right of the vertical bar represent the values on the right hand side of each equation in the final answer.
The numbers to the left of the bar represent the x and y coefficients of the equations. The first number of any given row is the x coefficient. The second number is the y coefficient.
For instance, the first row has 
to indicate the x coefficient is 1, and the y coefficient is 5. We end up with 1x+5y or simply x+5y. Putting everything together, the first equation would be x+5y = 11
Through similar steps, the second equation is 4x-6y = -3
the quotient will be x+3 and remainder is x^2+10x-100
MARK ME BRAINLIEST PLEASE
Add 2x^2 to both sides
7x^2-2x-6=9x
Subtract 9x from both sides
7x^2-11x-6=0
Factor by using slip and slide
x^2-11x-42
(x-14)(x+3)
(x-14/7)(x+3/7)
(x-2)(7x+3)
Then use the Zero Product Property to find roots
x-2=0
x=2
7x+3=0
7x=-3
x=-3/7
Final answer: x=-3/7, x=2
