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:
520 feet
Step-by-step explanation:
The area=16900
Area formula=b^2
b^2=16900
square root of 16900=130
130*4=520
Answer: c
Step-by-step explanation: 4/1 x 1/3 = 4/3
Answer:
If your looking at a graph, you find the slope by going to a random point, and using rise/run to go to the next point. A negative slope means the function is decreasing, and a positive slope means the function is increasing.
