Answer:
(2) Real and equal (i.e., repeated roots), if D = 0.
Step-by-step explanation:
.In a quadratic equation ax2 + bx + c = 0, if discriminant is D= b2 - 4ac, then roots of the quadratic equation are
Real and equal (i.e., repeated roots), if D = 0.
If the D > b² - 4ac then it's real and distinct.
Answer:
Each student gets 0.3 liters or 300 milliliters of orange juice.
Step-by-step explanation:
3 liters = 3000 milliliters

Answer:
10: -11n^5
12: 6k^2 -6k+7
Step-by-step explanation:
Ok so what your gonna do is add or subtract the ones with the same exponent.
so -15+4= -11 since they are both n^5 you can add them so your answer is:
-11n^2
now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)
8k^2-2k^2-5k-k+7
add like exponents
6k^2-6k+7
Answer:(x+1)(x+14)
Step-by-step explanation:
45 cars=454
Divide 45 on both sides to get the average length of a single car
1 car = 10.01 ft
