Answer:

1.x(x+1)=54,Quadratic equation

2.The price of the laptop is Php 20,400 the price of the android phone is Php 3,800

24,200-3,800=20,400

24,200-20,400=3,800

3.x(x-2)=80

10(10-2)=80

10(8)=80

4.W=5. L=10

L(W)=54

L=5+W

W(5+W)=54

Using the quadratic formula it will be:

W^2+2.5=54+2.5^2

W=5.26208734813, L=10.26208734813

5.L=72in

W=30 in

A= LW

2160= (42+W)(W)

W=30 in

L=30+42

L=72in
