The percentage increase when Mrs.Lay’s instagram followers went from 40 to 72 is 80%
<u>Solution:</u>
The percentage increase can be found out by dividing change in value by initial value. This is given as,

From question, we get

Final value of Mrs.Lay = 72
So percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is

Answer:
We will add 64 to both sides.
x=8±√20
Step-by-step explanation:
Here we are given the equation:

Now we take half of the coefficient of x and add it to x.
Coefficient of x is 16, half of 16 is 8.
Also we add square of 8 to both sides.
So new equation becomes:

Completing the square:

NOw let us simplify it to get the value of x.
Taking square root on both sides:

Bringing 8 to the right side:
x=8±√20

We can chang efractions to compare them by multiplying them by 1 or x/x where x=x so
1/2=7/12?
make bottom numbers equal
2 times what=12
divide 2
what=6
1/2 times 6/6=6/12
6/12=7/12
6=7
false
so therefor it does NOT equal 7/12
