Factor
x(2x-1)=0
x = 1/2, 0
Answer:
Center = (7, - 5)
Radius = 3
Step-by-step explanation:

X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8
Answer:
The other sides equal 9cm also because a square has four equal sides.
L=9cm * W=9cm =A
A=81 cm
28/20 in simplest form is: 7/5
70/50 in simplest form is 5/7
Because,
28/20 divided by 2 is 14/10, divided by 2 again is: 7/5
70/50 divided by 2 is 25/35, divided by 2 again is: 5/7
