If lauryn has purchased 4 books you have to do (2x-12)^4. Expand it to: (2x-12)(2x-12)(2x-12)(2x-12) multiply together. Then solve for x. If you need more help let me know.
<span> x^2 +(x-4)^2 =20^2</span>
<span> x^2 +(x-4)^2 =400</span>
x^2 +(x-4)^2 -400=0
factor:
2x^2-8x-384=0
Factor the 2 out of 2X^2
2(x-16) (x+12) =0
<span> Divide both sides by 2</span>
(x-16) (x+12) =0
X=16 , x=-12
<span> Number cannot be negative so x=16</span>
The answer is 25 as the numbers are consecutively being added. so on monday they did 5 and on sunday they did 7 (7-5=2) on sunday they did 7 and on monday they did 10 (10-7=3) and on monday they did 10 and on tuesday they did 14 (14-10=4)
