Which of the following statements are true of the discriminant? the discriminant is b2 – 4ac in the quadratic formula. the discriminant is the denominator in the quadratic formula. the discriminant is the radicand of the quadratic formula. the discriminant is the value under the radical in the quadratic formula. the discriminant is the value in front of the radical in the quadratic formula.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
