V=abc
a=2(ab+act+bc)
hope it helps
Answer:
B
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real irrational roots
• If b² - 4ac > 0 and a perfect square then 2 real rational roots
• If b² - 4ac = 0 then 1 real double root
• If b² - 4ac < 0 then 2 complex roots
Given
x² + 3x - 7 = 0 ← in standard form
with a = 1, b = 3, c = - 7 , then
b² - 4ac
= 3² - (4 × 1 × - 7) = 9 + 28 = 37
Since b² - 4ac > 0 then 2 real irrational roots
Answer:
45
Step-by-step explanation:
All you have to do is 1080/24 that gives you 45.
Answer:
I believe B is the correct answer ?
Step-by-step explanation:
Since the is a negative sign already there that turns the -3 into just 3 so the equation turns into 3-6 which is -3 so...
3-6<3.5
Subtract both like terms,
4qt-2qt will give us 2qt,
hope this help,
