Step-by-step explanation:
We know that
- Area of the rectangle=Length×Breadth
➝(x+4)(x-9)=68
➝x(x-9)+4(x-9)=68
➝x^2-9x+4x+-32=68
➝x^2-5x-32=68
➝x^2-5x=68+32
➝x^2-5x=100
➝x^2-5x-100=0
- The equation has no real roots hence this situation can't be possible
Answer:
2. Side length =9
Step-by-step explanation:
A square has all sides equal. and it has 4 sides, so 36 divided by 4 =9.
3.x squared =6
answer is x=3
square root both sides.
