Answer:
part a: 5
part b: no, ABC is not an equilateral triangle
Step-by-step explanation:
part a: if you do the distance formula for points A and B, you get 5
part b: using the distance formula again, points A to B and points A to C are both 5, but points B to C is 6, therefore it's not equilateral because all the sides have to be the same length
Answer:
x = all real numbers because this equation is an identity
Step-by-step explanation:
9 (1/3) = 9*1/3 = 3
3 + 8x = 4(2x + 3/4)
3 + 8x = 8x + 3
x = all real numbers because this equation is an identity
speed is 45 miles per hour. 135/45=3, so the answer is 3hours (A)
Answer:
C. 
- 4 - 24x + 21
Step-by-step explanation:
(x - 7)(
+ 3x - 3)
x( + 3x - 3) + -7( + 3x - 3)
( + 3 - 3x) + (-7 + -21x + 21)
- 4 - 24x + 21
