Answer:
$2
Step-by-step explanation:
the unit rate would be 2 dollars each bag of chips because 2 times 2 is 4
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:
119j+28
Step-by-step explanation:
7(17j+4) Remove the parentheis
distribute 7 through the parentheis
2/7 + 4/7 = 6/7 Can be rewritten as
4/7 + 2/7 = 6/7
