Melissa is planting a rectangular vegetable garden with a square patch for tomatoes. She wants the length of the garden to exceed three times the length of the tomato box by 2 feet. She also wants the gardens width to exceed the width of the tomato patch by 5 feet. If the area of the vegetable garden is 170 square feet, which equation could be used to find the length of the tomato patch?
0=3x^2-160
0=3x^2+180
0=3x^2+10x+180
0=3x^2+17-160
