Step-by-step explanation:
Answer:
Option a is the correct answer.
Step-by-step explanation:
Let x,y and z represent the marks scored in first,second and third tests respectively.
Total score is 239, then:
x+y+z = 239 -------1
Combined scores of first and second tests is 59 more than that of third test,then:
x+y = 59+z
x+y-z = 59 ---------2
The score of second test is 25 more than that of third test, then:
y = 25+z
0x+y-z = 25 --------3
The matrix equation for this situation is:

Answer:
C. 6 cm and 7 cm
Step-by-step explanation:
(4 cm)² = <em>16 cm²</em>
(5 cm)² = <em>25 cm²</em>
(6 cm)² = <em>36 cm²</em>
(7 cm)² = <em>49 cm²</em>
(8 cm)² = <em>64 cm²</em>
Out of these values, 46.3 cm² is between 36 cm² and 49 cm², so it is safe to say that the side length is between 6 cm and 7 cm, as this side length's square is between the square of 6 cm and 7 cm.
