7 1/8 is greater than 7.025
The answer is B)422 ,you're welcome :)
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:
The answer is a² .
Step-by-step explanation:
You have to substitute x and y into the expression :



Next, you have to apply Basic Trigonometric Identity :




Answer:
So put what is order from least to greatest we have to have something to look off, you cant expect someone to just give you the answer? this could mean something for over 1 million different questions please provide more information.
