(x - 1)2 = 4<br> how do i do this
Gnoma [55]

Answer:

x = 3

Step-by-step explanation:

(x - 1)2 = 4

how to get this solved is very simple.

first step to apply is the BODMAS RULE

B..................... bracket

O..................... of

D.....................Division

M.................... multiplication

A..................... addition

S.................... Subtraction

so (x - 1)2 = 4

we have,

2x - 2 = 4 ( by opening the bracket)

collect the like terms

2x = 4+2

divide both sides by 2

2x/2 = 6/2

x = 3

to check if your answer is correct put the value of x = 3 into the question and see if the right hand side will equal to the left handside

(x - 1)2 = 4

(3-1)2=4

2(2)=4

4=4.............................. proved

Rationalize the denominator:<br><br> Please give step by step solution
MrMuchimi

Answer:

1 + i

Step-by-step explanation:

To rationalize multiply numerator and denominator by (2 + i )

\frac{3+i}{2-i}= \frac{3+i}{2-i} \times \frac{2+i}{2+i} = \frac{(3+i)(2+i)}{(2-i)(2+i)} = \frac{6+3i+2i-1}{4-(-1)} = \frac{5+5i}{5} = 1 + i

How many kilometers did they drive per hour
Elza [17]
The distance from San Francisco to New York is 4140 km. Since the question asks how long it took the Humphrey family in km/hr (kilometers per hour), you would just divide 4140km by 6.
Why? Because it took them 6 hours to make a trip of 4140 km. Dividing 4140 by 6 gives you the distance they traveled per hour.

690 km/hr
