First simplify the equation and next multiply the 20 with the x^2 and find a number that adds together to give you the middle
Answer:
the first one is 37
the second one is 36
the third one is 27
Step-by-step explanation:
Answer:
B. $136,960.54
Step-by-step explanation:
Rate = r = 4%
Times = b = 4
Future Value = A = $315,930
No. pf Years = n = 21
Present Value = P = ?
A = P [1 + (r / b)]ⁿᵇ
$315,930 = P [1 + (0.04 / 4]²¹ ˣ ⁴
$315,930 = P [1 + 0.01]⁸⁴
$315,930 = P [1.01]⁸⁴
$315,930 = P x 2.306723
P = $315,930 / 2.306723
P = $136,960.54
plug in the x for all of those to find y
= 7√(2x) + 2x
or
= 2x + 7√(2x)
answer is A. 2x + 7√(2x)
