4x^2-5x=-1
4x^2-5x+1=0
4x+2.24x=1
6.24x=1
x= 0.16025641025641025641025641025641
That would be an acute triangle because all the angles are less than 90 degrees I hoped this helped
Answer: The answer is (D) ![24x+2.](https://tex.z-dn.net/?f=24x%2B2.)
Step-by-step explanation: Given that there is a rectangle, where length of the rectangle is given by
![\ell=4x+5,](https://tex.z-dn.net/?f=%5Cell%3D4x%2B5%2C)
and width of the rectangle is given by
![b=8x-4.](https://tex.z-dn.net/?f=b%3D8x-4.)
We are to find the perimeter of the rectangle. To do so, we need to add two times length with two times breadth of the rectangle.
Therefore, perimeter is given by
![p=2\ell+2b=2\times(4x+5)+2\times(8x-1)=8x+10+16x-8=24x+2.](https://tex.z-dn.net/?f=p%3D2%5Cell%2B2b%3D2%5Ctimes%284x%2B5%29%2B2%5Ctimes%288x-1%29%3D8x%2B10%2B16x-8%3D24x%2B2.)
Thus, the correct option is (D).
Answer:
it is not a function
Step-by-step explanation:
because the element 2 has not ot unique image
Answer: -2
Explanation: On the image we can see it goes down 4 units and right 2. Giving us the slope ![\frac{-4}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-4%7D%7B2%7D)
Simplified that is -2 which is the slope of the line
