This is false because 20-8 is 12 and 12 times 5 isnt 17
Expected is -3
Expect to lose $3… bad game right there!
- Discriminant Formula: b² - 4ac, with a = x^2 coefficient, b = x coefficient, and c = constant
So firstly, using our equation plug in the values into the discriminant formula and solve as such:
(-7)² - 4 × 3 × 4
49 - 48
1
So our discriminant is 1. <u>Since 1 is positive and a perfect square, this means that there are 2 real, rational solutions.</u>
Triangles add up to 180°, so the answer is 67
The appropriate compatible numbers to use to estimate would be 20(1/2)
estimated product is 10, took the quiz :)
