Ok, but i think you explained it bad, tag me again so i can answer
Answer:
discriminant: 64
Step-by-step explanation:
The discriminant of a quadratic is the expression inside the radical of the quadratic formula.
b^

Simplify each term.
Raise −
8 to the power of 2.
64 − 4 (
6 ⋅ 0
)
Multiply 6 by 0
.
64 − 4 ⋅ 0
Multiply −

Answer:
Since ABCD is a top face cube
EFGH is a buttom face cube
Now
Diagonal through interior is:
Side AG,CE,FD&BH
So your answer is:
<u>Side C E</u>
<u>Side C ESide D F</u>
Answer:
depth = 6th + 2(number of years)
Answer:
1) (x + 4)(x - ½) = 0
4x² + 16x = 0
2) 0.25x² + 0.8x - 8 = 0
3x² - 4x = 15
Step-by-step explanation:
1) (x + 4)(x - ½) = 0
x = -4, ½
4x² + 16x = 0
4x(x + 4) = 0
x = 0, -4
2) (x - 6)(x + 9) = 0
x = 6, -9
(x - 1)² = 4
(x - 1)² - (2)² = 0
(x - 1 - 2)(x - 1 + 2) = 0
(x - 3)(x + 1) = 0
x = 3, -1
These two are easier to solve using product = 0 property, while the other two would be easier using the quadratic formula
