Answer:
145
Step-by-step explanation:
The discriminant of quadratic ...
ax^2 +bx +c = 0
is ...
d = b^2 -4ac
For your quadratic, you have a=4, b=-7, c=-6, so the discriminant is ...
d = (-7)^2 -4(4)(-6) = 49 +96 = 145
The discriminant is 145.
Squares are:
1. Equal on all 4 sides
2. All Have the same angle measure of 90 degrees
D) 54 degrees:
BD+AB+DE+2ACE" on the circumference twice on the center"=360
28+112+112+2ACE=360
2ACE=108
∠ACE=54
