<span> When area is equal 1120. We can write an equation
(x+4)(-x+64)=1120
-x²-4x+64x+256=1120
-x²+60x+256-1120=0
-x²+60x-864=0
D=b² - 4ac= 3600-4*864=144, √D=12
x= (-b+/-√D)/2a
x=(-60+/-12)/(-2)
x=24, x=36
For x=24
(x+4)=24+4=28
(-x+64)=(-24+64)=40
For x=36
(x+4)=36+4=40
(x-64) =(-36+64)=28
So sides should be 28 and 40 in.
We did not get any extraneous solutions. They could be if we get negative length side, for example. They can come because a quadratic equation can
give positive and negative numbers because a^2  and (-a)^2 give the same positive number.
We chose to solve this equation using formula for quadratic equations, because this equation has too big numbers to solve it using other methods.

mixas84 [53]

Answer:

Bonus of Brianna = 125 $

Explanation:

 Amount of Brianna's yearly bonus = 155$

 Amount taken away for each customer care complaint = 2.50$

 Number of complaints received against Brianna in the year = 12

 Total amount lost by Brianna due to complaint = 12*2.50 = 30$

 Amount of bonus received by Brianna after reduction of complaint loss = 155-30 = 125$

  Bonus of Brianna = 125 $
