Question

The area of a rectangle is given by A = 8 x²− 2 x − 15. If the length was larger than the breadth, then the length can be​

Answer 1

Step-by-step explanation:

Let the shorter side is triangle=x cm

The other of side of the triangle=(x+5)cm

Area of Rectangle=(x×5)(x)=150

=>x

2

+5x-150=0

=>(x+15)(x-10)=0

=>either x=-5 or x=+10

since the side cannot be negative

Hence,the value of c=-15 is negligible

When x=10cm then the outer side=10+5=15 cm
