Answer: I'm serious, where is your question? no question posted here sir.
B
given a quadratic equation in standard form
ax² + bx + c = 0
Then we can describe the nature of the roots using the discriminant
Δ = b² - 4ac
• if b² - 4ac > 0, then 2 real, distinct and irrational roots
• if b² - 4ac > 0 and a perfect square, then real and rational roots
• if b² - 4ac = 0, then real and equal roots
• if b² - 4ac < 0, then roots are not real
for x² + 9x + 14 = 0
with a = 1, b= 9 and c = 14, then
b² - 4ac = 9² - (4 × 1 × 14 ) = 81 - 56 = 25
Since b² - 4ac > 0 and a perfect square, then roots are real and rational
Answer:
271
Step-by-step explanation:
If the decimal in the tenths place is less than 5, the number will not be rounded.
Well 125 is 100 + 25. Put those into decimal form, separately, then add them together.
100 --> 1.0
25 --> 0.25
1.0 + 0.25 = 1.25
Change from decimal to fraction form:
1.25 --> 1&1/4
In the first one the answer is letter B, if you divide 255 by 3 is gonna give you 85 then multiply 85 x 50 and its gonna give you 4,250. Let me know if im good or wrong. Have a great day :)
