Write a system of linear equations that models the situation. Do not solve.An isosceles triangle has a perimeter of 29 inches. The shortest side is 7 inches shorter than either of the other two sides. Find the length of each side of the triangle (recall that an isosceles triangle has two sides with equal measure).
A. 2x + y = 29 x - y = 7 B. 2x + 2y = 29 x - y = 7 C. x + y = 29 x + y = 7 D. x + 2y = 29 x - y = 7
Write the equation in standard form.y2 - 16x + 64 = 0
