13
50 - 13 = 37
The last one is that correct answer.
2x^2 +7x -4
The question is asking to state the two numbers that the product would be 18, base on my calculation, the possible answer would be 2 * 9, 1 * 18 and 3*6. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications. Have a nice day
For this case we have that the area is given by:
A = (w) * (l)
Where,
w: width
l: long
Substituting we have:
66 = (w) * (w + 5)
Rewriting
w ^ 2 + 5w - 66 = 0
(w + 11) * (w-6) = 0
Using the positive root we have:
w = 6
Answer:
the width of the frame is:
w = 6 cm
