Answer: 29
Step-by-step explanation:
116=4n
(Divid both sides by 4)
29=n
b- x = −5 and x = 5
c- x = −4 and x = 4
d- x = −1 and x = 9
A. 1.1, 9.1
B. 1.1, -9.1
c. -1.1, 9.1
D. -1.1, -9.1
Answer: The correct option is (B) 1.1, -9.1.
Step-by-step explanation: We are given to solve the following quadratic equation by the method of completing the square.
In completing the square method, we need to make left hand side of the above given equation as a perfect square trinomial.
From equation (i), we have
Rounding to the nearest tenth, we get
Thus, the required solution is x = 1.1, -9.1.
Option (B) is CORRECT.
A metre = 100 centimeters.
If you say your desk measures 46cm:
