You just have to add the two numbers ad divide by two!
X is the hypotenuse of an isosceles triangle. The length of the sides are the difference of the inner and outer squares divided by 2. Which means that the sides of the triangle is 1.5 inches. Using that information, the length of X can be deduced to be 2.12 inches using Pythagoras theorem
Its the second choice down. x is an element of the intersection of B and C. A is not part of that, and since B and C overlap, it's the intersection, not the union (U).
Answer:
x=1, x=-4
Two distinct real roots
Step-by-step explanation:
x² + 3x- 4 = (x - 1)(x + 4)
x=1, x=-4
Two distinct real roots
I think it’s C sorry if I’m wrong
