Answer:

{x}^{2}  - 4x = 7 {x}^{2}  + 8x \\  {x}^{2}  - 7 {x}^{2}  = 8x + 4x \\  - 6 {x}^{2}  = 12x \\  - 6x = 12 \\ x =  \frac{12}{ - 6}  =  - 2 \\ x =  - 2 \\ thank \: you

While shopping at a clearance sale, Samantha finds a $60.00 dress on sale for 25% off. Samantha also has a 50% off coupon. Which
liq [111]

It seems most likely that ...

... Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction

_____

In the real world, it seems probable that Samantha will be offered the choice of using the coupon <em>or</em> the sale discount. If she chooses tht 50% coupon, her savings will be $30. If she chooses the marked sale discount, her savings will be $15.

The scenario above assumes she gets 50% off the sale price of $45, so saves $15+22.50 = $37.50 off the original price.
