X2 − 15x = −50 A) x = 3, x = 5 B) x = 5, x = 10 C) x = 3, x = −5 D) x = −5, x = −10

x = 10 or x = 5 thus: B is the answer

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 15 x = -50

Add 225/4 to both sides:

x^2 - 15 x + 225/4 = 25/4

Write the left-hand side as a square:

(x - 15/2)^2 = 25/4

Take the square root of both sides:

x - 15/2 = 5/2 or x - 15/2 = -5/2

Add 15/2 to both sides:

x = 10 or x - 15/2 = -5/2

Add 15/2 to both sides:

 x = 10 or x = 5

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
