$848-d is the answer.
Since there is not set amount for the expenses, the only answer I can give is this equation.
34.76
o
, nearly.
Explanation:
Angle of elevation = arc tan( (vertical height)/(length os the shadow)).
Here, this angle is
arc tan (12.5
/
18) =
34.78

, nearly
Assuming this question associates "solutions" with "zeros", then the answer is
x^2 + 2x + 3
======
If we set x^2 + 2x + 3 to equal 0, we have
x^2 + 2x + 3 = 0
The discriminant of this equation of the form ax² + bx + c = 0 is
discriminant = b² - 4ac = 2^2 - 4(1)(3) = -8
The discriminant is negative, so there are no real solutions (the discriminant is under a square root in the quadratic equation; square root of a negative number is not a real number)
Marty read 4 times as many pages as Nelson and Jennifer COMBINED. Marty read 1,860 pages.
In total, after dividing Marty's total by 4, Jennifer and Nelson both read a total of 465 pages.
After subtracting Nelson's 240, Jennifer is then found to have read 225 pages.
B would be the best viable option, as it clearly shows that 240+?x4=1,860, which it does.
Hope this helped. Khan Academy is a great resource for any learner. :)
