Refer to the parallelogram at the right to answer problems 6 and 7. 6. What is the area of the parallelogram? 13 mm 12 mm 7. What is the perimeter of the parallelogram? 15 mm D1111 and intorcented by linen Anita hegan at point A and rap around the field​

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
