Answer:
<h3>x = -2 and 7</h3>
Step-by-step explanation:
- x^2 - 5x - 14 = 0
- x^2 - ( 7 - 2 )x - 14 = 0
- x^2 - 7x + 2x - 14 = 0
- x ( x - 7 ) + 2(x - 7) = 0
- (x + 2) (x - 7) = 0
- x = -2 and 7

Answer:
Multiple choice questions = 5
True questions = 15
Step-by-step explanation:
Given that:
Total number of questions = 20
Total worth of point = 100
Multiple choice questions (M) = 11 points each
True false questions (T) = 3 points each
Hence,
M + T= 20 ____(1)
11M + 3T = 100 ____(2)
M = 20 - T
Using the relation in (2)
11(20 - T) + 3T= 100
220 - 11T + 3T= 100
220 - 8T = 100
-8Tf = 100 - 220
-8T = - 120
T = 120/8
T = 15
Mc = 20 - 15
Mc = 5
Multiple choice questions = 5
True false questions = 15
