Answer:
x = 5±2√7
Step-by-step explanation:
This quadratic cannot be factorised via the factorisation method, so we use the quadratic formula :
x = 
or x = 
(The reason I did 2 equations is because brainliest does not allow me to do the ± in the equation insert thing )
x = 
or x = 
x = 
or x= 
x = 
or x = 
x = 
or x = 
Hope this helped and brainliest please
Answer: C
Step-by-step explanation: The standard equation is Ax + By = C
To solve for this, first solve for the slope: y2 - y1 / x2 - x1
0 - 5 / 4 - 0 = -5 / 4
Plug the slope and ordered pair of (0, 5) into the equation y - y1 = m(x - x1)
y - 5 = -5/4(x - 0)
Add 5 to both sides: y = -5/4x + 5
Subtract y and 5: -5 = -5/4x - y
Multiply the entire equation by 4: -20 = -5x - 4y
(or multiply entire equation by -4 to get 20 = 5x + 4y)
In any rhombus, the four sides are the same length.
Because of this, we know that
Furthermore, AC = AC due to the reflective property
Those three facts then allow us to prove triangle ACD is congruent to triangle ACB through the SSS congruence property. Then from CPCTC, we then know that angle DAC = angle BAC, which is enough to show that AC bisects the angle shown. The term "bisect" means "cut in half".
I think it's 2,5,6 because a rational number is a number that can be put in a fraction.
Examples:
3/7 (3 over 7)
-2/5 (-2 over 5)
And 4, which can be put as 4/1 (4 over 1) in fraction form
