Find the solution(s) to the equation. -x2 - 4x - 3 = 0 GA -6, -2 O B -3, -1 OC 1, 3 O D -4. 0 Determine the nature of the roots of the equation. 4x2+32x+64=0 OA no real solutions 0 B a unique real solution 0 C two distinct real solutions O D cannot be determined A landscaper is designing a flower garden in the shape of a trapezoid. She wants the shorter base to be 3 yards greater than the height and the longer base to be 7 yards greater than the height. She wants the area to be 155 square yards. The situation is modeled by the equation h2 + 5h = area. Use the Quadratic Formula to find the height that will give the desired area. Round to the nearest hundredth of a yard. 0 A 20.40 yards 0 B 10.20 yards 0 C 320.00 yards 0 D 12.70 yards 4. Solve. Check for extraneous solutions. 6x = 24 + 12x OA 1 OB OC -1 OD 1 and - 5. Solve the equation. 4(3-x)3 -5=59 OA -5, 11 OB 5 Oc 11 OD -11 6. Solve the equation. If there is no solution, write no solution. 4 x + = = 20 OA x=4- or -5 3 OB X=4- 12 oc no solution OD x=411 or - 4 41 12 12
