You are right, it's C. I checked in geogebra bro/girly/dude.
Hope this helps !

2.40 divided by 6 is 0.40 so 0.40 times 10 is 4.00
Basically that answer is incorrect. If you'd learn about combining, multiplying, dividing or subtracting like terms, this will be a simple problem. To be specific, like term is a number with a letter with it.
For example, 2.4z is a like term.
so you can only add like term, not any other normal number. When two terms have the same "letter", you will have to do what the sign said so in the problem....
2.4z + 1.2z - 6.5 = 0.7
3.6z - 6.5 = 0.7 (Add but leave the z alone because you are not multiplying)
The final answer is 3.6z - 6.5 because you cannot do anything else to that problem.
3.6z-6.5=0.7 is not true.
Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots
