BackAnswer each question. Sides of a Right TriangleTo solve for the lengths of the right triangle sides, which equation is correct?
A. x^2=(2x-2)^2+(x+4)^2 B. x^2+(x+4)^2=(2x-2)^2 C. x^2=(2x-2)^2-(x+4)^2 D. x^2+(2x-2)^2=(x+4)^2
Dimensions of a Right Triangle The shortest side of a right triangle is 7 in. shorter than the middle side, while the longest side (the hypotenuse) is 1 in. longer than the middle side. Find the lengths of the sides.
Evaluate the discriminant for each equation. Then use it to determine the number and type of solutions. 16x² +3 = -26x
Evaluate the discriminant for each equation. Then use it to determine the number and type of solutions. 8x² = -2x -6
See Exercise 47. (b)Which equation has two nonreal complex solutions?
Which equation has two real, distinct solutions? Do not actually solve.
A. (3x-4)² = -9 B. (4-7x)² = 0 C. (5x-9)(5x-9) = 0 D. (7x+4)² = 11
Solve each equation. (x+4)(x+2) = 2x
Match the equation in Column I with its solution(s) in Column II. x2 = 25
Match the equation in Column I with its solution(s) in Column II. x2 = -25
Match the equation in Column I with its solution(s) in Column II. x2 - 5 = 0
