Answer:
Zeroes: ± 6
Step-by-step explanation:
The given polynomial is: 
.
To find the zeroes of the polynomial we equate it to zero.
⇒ 
⇒
⇒ x = -6 and x = +6. They are the zeroes of the polynomial.
Since 
is a quadratic equation it will have two roots. Therefore, the roots are x = -6, -6.
Multiplicity of a root is the number of times the root appears as the solution for the equation.
This makes x = -6 as root with multiplicity two.
Similarly, 
will have three roots.
∴ x = +6, +6 , +6
x = +6 is a root with multiplicity three.
Answer:
2.4
Step-by-step explanation:
Let the perimeter and the area = x.
L = 12
P = 2(L + W) = x
P = 2(12 + W) = x
A = LW = x
A = 12W = x
2(12 + W) = 12W
12 + W = 6W
5W = 12
W = 2.4
Answer: 2.4
a) Two angles are said to be complementary if their sum is equal to 90°
Given : 2x and 4x are complementary angles
⇒ 2x + 4x = 90°
⇒ 6x = 90°
⇒ x = 15°
<u>Answer</u>: The two angles are : 30° and 60°
b) Two angles are said to be supplementary if their sum is equal to 180°
Given : x and 5x are supplementary angles
⇒ x + 5x = 180°
⇒ 6x = 180°
⇒ x = 30°
<u>Answer: </u>The two angles are : 30° and 150°
c) Two angles are said to be complementary if their sum is equal to 90°
Given : x and x + 50° are complementary angles
⇒ x + x + 50° = 90°
⇒ 2x = 40°
⇒ x = 20°
<u>Answer:</u> The two angles are : 20° and 70°
d) If two angles form a linear pair, then the sum of the angles should be equal to 180°
Given : 2x + 10° and 3x + 10° form a linear pair
⇒ 2x + 10° + 3x + 10° = 180°
⇒ 5x = 160°
⇒ x = 32°
⇒ 2x + 10° = 2(32) + 10° = 74°
⇒ 3x + 10° = 3(32) + 10° = 106°
<u>Answer:</u> The two angles are 74° and 106°
