Answer:
rhombus
Step-by-step explanation:
A rhombus had EQUAL four sides yet no right angles. Why not trapezoid? Well, a trapezoid doesn't have four equal sides. Square and rectangle aren't the answer because they contain right angles. Hopes this helps!
Wherever the line hits on the horizontal line on a graph.
The order is -1.4, -3/5, 1/4, 0.9, and 9/2. So
D is the correct answer
Answer:
the answer is b
Step-by-step explanation:
Answer:
- there are 4 complex solutions
- 3 real zeros and 2 complex zeros
Step-by-step explanation:
1. Descarte's rule of signs tells you there are 0 positive real roots and 0 or 2 negative real roots. (for positive x, signs are ++++ so have no changes; for negative x, signs are ++-+, so have 2 changes.) A graph shows no real roots.
2. There are 3 sign changes in the given polynomial, so 3 or 1 positive real roots. When the sign of x is changed, there are 2 sign changes, so 0 or 2 negative real roots. A graph shows 2 negative and one positive real root (for a total of 3), so the remaining 2 roots are complex.
