Solve the equation using the Quadratic Formula. x2 - 8x + 15 = 0 Select the correct choice below and, if necessary, fill in the
Ahat [919]

Answer:

x = (5,3)

Step-by-step explanation:

the quadratic formula is x =( -b±√(b^2-4ac))/2a

to solve for x, a=1, b=-8,c=15

x =( -(-8)±√((-8)^2-4*1*15))/2(1)

x=8 ± √(64-60))/2(1)

x=(8 ± √(4)) / 2

x=(8 ± 2) / 2

solve with '+'

x=(8 + 2) / 2 = 10/5 = 5

solve with '-'

x=(8 - 2) / 2 = 6/2 = 3

x = (5,3)

Convert 2032four to base 10
Burka [1]
The easiest way is a successive division by 4:


1st division: 2032/4 = 508 and 0 (0 is the  1st Remaining)

2nd division 508/4 = 127 and 0 (0 is the   2nd Remaining) 

3rd division 127/4 = 31 and 3 (3 is the   3rd Remaining)

4th division 31/4 = 7 and 3 (3,  is the  4th Remaining)

5th division 7/4 = 1 and 3 (3 is the  5th  Remaining)

Now you write the last quotient (the 5th) , that is 1 and add to it all remaining starting from the 5th , backward to the 1st remaining,
