Solve the quadratic equation. (x + 6)2 = 49
kykrilka [37]

Answer:

C

Step-by-step explanation:

To solve, use inverse operations:

(x+6)^2=49\\\sqrt{(x+6)^2} =\sqrt{49} \\x+6=+/-7

Now we solve for both +/- 7.

x+6=7

x=1

x+6=-7

x=-13

Molly earns a rebate each month on her movie tickets and books. She earns $0.25 for each movie ticket and $2 for each book. Last
stiv31 [10]

Answer:

8 books

Step-by-step explanation:

Earning for each ticket is $0.25 and for each book is $2

If total earning for 4 tickets and x books is $17, then the equation is:

  • 0.25*4 + 2x = 17
  • 1 + 2x = 17
  • 2x = 16
  • x = 16/2
  • x = 8

So Molly purchased 8 books
