Answer:
4
Step-by-step explanation:
Descarte's rule of signs tells you that there will be 0 or 2 positive real roots and 0 negative real roots. A graph shows there are no positive x-intercepts, so 0 real roots.
All four roots are complex.
The chords SR and ST are congruent, so the (minor) arcs SR and ST have the same measure.
The measure of the arcs SR, ST, and RT add up to 360º. So we have
2<em>x</em>º + 64º = 360º ==> <em>x</em> = 148

-2x-14
Step-by-step explanation:
Answer:
5 units
Step-by-step explanation:
To solve this we can use pythagoras theory:
- a² + b² = c², where c is the diagonal
- 3² + 4² = c²
- 9 + 16 = 25
- c² = 25, so c = √25
- c = 5
Hope this helps!
