Answer:
D. 29
Step-by-step explanation:
180 - 151 = 29
<span>2x^2 + 3x + 5 = 0
a = 2 b = 3 and c = 5
x = [-b +-sq root(b^2 -4ac)] / 2a
</span><span>x = [-3 +-sq root(9 -4*2*5)] / 4
x = [-3 +-sq root(9 - 40)] / 4
</span><span>x = -(3 / 4) + sq root (-36) / 4
</span><span>x = -(3 / 4) - sq root (-36) / 4
</span>
By doing so, they provide the illusion that the payments are cheaper then 1000 dollars, because 50 looks very small, when in reality it's $100 more then what the mattress is actually worth.
With rational coefficients (a, b and c), if one zero is rational, that means the discriminant is rational. We can conclude that the other is also rational.
Answer:
12/5 pounds
Step-by-step explanation:
To solve this, let's find out how many pounds of rice are in 1 serving, then multiply this by 30. We get 2/25 pounds of rice in 1 serving, and we can just multiply this by 30 to get 12/5 pounds of rice.
