Answer:
p = 30
angles 30°, 45°; exterior: 75°
Step-by-step explanation:
The exterior angle is equal to the sum of the remote interior angle:
3p -15 = p + (p +15)
p = 30 . . . . . . . . . . . . . add 15-2p
The interior angles are 30°, 45°; the exterior angle is 75°.
Answer:
42x^2 - 7x - 6x + 1
42x^2 - 13x + 1 for FOIL method
To solve for x
7x - 1 = 0
7x = 1
x = 1/7
6x - 1 = 0
6x = 1
x = 1/6

Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students
