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
Answer:100%. Probability
Step-by-step explanation:
Emily = aa
Man = AA
After crossing the two, the result wI'll be Aa, Aa, Aa, Aa
Since every result has a carrier(a) in it, makes it 100% probability.

Answers: Choice C, Choice D, Choice F</h3>
What these expressions have in common is that their exponents multiply to 16
- (-4)*(-4) = 16 for choice C
- (-2)*(-8) = 16 for choice D
- 8*2 = 16 for choice F
The rule used here is (a^b)^c = a^(b*c). We multiply the exponents and keep the base the same.
