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
The first one is 12,and the second 24....dont worry about marking me as brainliest just thank me lol
Hi!
5x = 1/4
5x = 0.25
<h3>Divide by 5 on both sides</h3>
5x/5 = 0.25/5
x = 0.05
<h3>Convert 0.05 to a fraction</h3>
5/100
<h3>Simplify the fraction</h3>
1/20
<h2>The answer is X=1/20</h2>
Hope this helps! :)
