⇒x=8 and x=-13
Neglecting the negative value, we have the width of the rectangular storage room=x=8 feet.
Therefore, the length of the rectangular storage room=x+5=8+5=13 feet.
So, the dimensions of the room are 8 feet and 13 feet.
Answer:
The fourth graph (last graph)
Step-by-step explanation:
Remember that the zeros of a function are the x-intercepts of the graph. To find the zeros we just need to set the function equal to zero and solve for x:
Now we know that the graph or our function intersects the x-axis at x = 1 and x = -4.
Since both x values inside the parenthesis are positive, our parabola is opening upwards.
The only graph opening upwards whose x-intercepts are x = 1 and x = -4 is the fourth one.
We can conclude that the graph of is the fourth one.
