(c) x = -b/a

Given, ax + b = 0

Transposing b to RHS and it becomes -b

Then,

ax = -b

x = -b/a

(c) 4x + 7 = x + 2

Transposing 7 to RHS and it becomes -7 and x to LHS it becomes -x

4x – x = 2 – 7

3x = – 5

X = -5/3

So, -5/3 is neither a fraction nor an integer.

The adjacent sides of a parallelogram are 5 cm and 9 cm. Its perimeter is 28 cm.

We know that, perimeter of Parallelogram = 2 × (sum of lengths of adjacent sides)

= 2 × (5 + 9)

= 2 × 14

= 28 cm

The number of sides in a regular polygon having measure of an exterior angle as 72o is 5.

We know that, the measure of each exterior angle of a regular pentagon is 360o/n.

Where ‘n’ is the number of sides in the polygon,

Then, pentagon has exterior angle = 72o

So, 72o = 360o/n

n = 360o/72o

n = 5

The number of diagonals in a hexagon is 9.

We know that,

The number of diagonals in a polygon of n sides is n(n – 3)/2

Where n = 6

Then,

= 6 × (6 – 3)/2

= 6 × 3/2

= 18/2

= 9

The measure of each angle of a regular pentagon is 108.

We know that, the sum of all the angles of a polygon is (n – 2) × 180o.

Where ‘n’ is the number of sides in the polygon,

Then, pentagon has 5 sides, i.e. n = 5

So, (n – 2) × 180o

(5 – 2) × 180o

3 × 180o

540o

Measure of each angle = 540o/5 = 108o

Test management most commonly refers to the activity of managing a testing process.

A test management tool is software used to manage tests (automated or manual) that have been previously specified by a test procedure.

It is often associated with automation software.

Test management tools often include requirement and/or specification management modules that allow automatic generation of the requirement test matrix (RTM), which is one of the main metrics to indicate functional coverage of a system under test (SUT).

The number of sides of a regular polygon, where each exterior angle has a measure of 36o, is 10.

We know that, the measure of each exterior angle of a regular polygon is 360o/n.

Where ‘n’ is the number of sides in the polygon,

Then, exterior angle has a measure of 36o

So, 36o = 360o/n

n = 360o/36o

n = 10

NO
