What are the solutions of the quadratic equation (x + 3) = 49,

x = -10    x=4

Step-by-step explanation:

(x + 3) ^2= 49

Take the square root of each side

sqrt((x + 3)^2) =±sqrt( 49)

(x + 3) =±7

Separate into two equations

x+3 = 7              x+3 =-7

Subtract 3 from each side

x+3-3 =7-3         x+3-3 =-7-3

x =4                      x=-10

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
