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:
Answer c..... can i get brainliest ?
Step-by-step explanation:
Just substitute (2,0) in the equation
2 for x
0 for y
A.) -5/8 = -5/8 or 5/-8
b.) -7/-10 = 7/10
First, let's convert X into 4
(3*4 - 4)ft, (4*2 - 1)ft, (2*4*2 - 15)ft
Now lets simplify this a little
(12 - 4)ft, (8 - 1)ft, (16 - 15)ft
Awesome now lets finish up
8 x 9 x 1 / 2 = 36
The answer should be 36ft. Unless I did my math wrong.
The answer is d that’s the right one
