5 times (-17)= -85 so you should have said -85
The formula for percent error is the absolute vale of: theoretical-experimental and the result of that divided by the theoretical so it is 120-94=26 and divide that by 120 and it is .216 so round up to .22 and then multiply by 100 which is 22 so 22%
(I think)
The discriminant is b^2-4ac
In this equation 9=a, 12=b, 4=c
Plugging into the formula
12^2-4(9)(4)=
144-324 =
-180 is the discriminant
Since the discriminant is a negative number there are no real roots
A and d.
as 6(a+12) and 3(2a+4) both are equivalent to 6a+12
b. 6a + 72
c. 12 + 6a
e. 6a + 36
The correct answer is going to be D.
