I always start by moving the last term to the other side
To complete the square you take term 'b' , divide it by 2 then square it
= 25
We have to add 25 to what we have and what you do to one side you have to do to the other
Now we factor what is on the left side of the equation
The last step is to move our right side of the equation back over
- which is your answer :)))
A.450.80
Multiply 40x9.80=392
Take 1/2 of 9.80 that equal 4.90
4.90 plus 9.80 $14.70x4=58.80
$58.80 plus 392 equals 450.80
Answer:
40 or 48 if it has to be greater than 40.2
Step-by-step explanation:
40- .2=40
40/8=5
~or~
40.2+7.8=48
48/8=6
Let R be the greater radius and r be the smaller radius
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2
