You would divide 1350 by 47 to find our how many strings of lights she would need.
1350 / 47 = 28.7234
note that IF you choose 28, you would run short because it would not be enough to cover all of that edge.
so you would need to round up to 29
therefore our answer would be D)29 strings of lights.
Answer: 20,-13
Step-by-step explanation:
We can rewrite the problem as an equation. This equation is x(x-7)=260 (x being the mystery number). We can simply this into x^2 -7x=260. We can then rewrite this as x^2 -7x -260=0. We need to find the roots of this quadratic, which are -13 and 20. You can find this by factoring the quadratic.
