discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots
Daniel would be 6 daniel was 1 year 2 years ago 1x4=4 plus put on the 2 years =6
I don't know. But I know how to find it. Let's work it out together:
<u>5x = 2x + 20</u>
Subtract 2x from each side: 3x = 20
Divide each side by 3 : <em>x = 20/3</em> or ( 6 and 2/3 ).
Answer:
22
Step-by-step explanation:
(5x-7 )+(4x-11)=180 ( it equals 180 because those two angles equal 180)
Then add the similar things together
5x+4x=9x
-7-11= -18
9x-18=180, add 18 on both sides to get 9x alone
9x=180, then divide 180 by 9 to get x alone
x=22
