Answer:
8) 10c² - 2c + 5
9) 5a²b² - ab²
Step-by-step explanation:
8c² - c + 3 + 2c² - c + 2 =
10c² - 2c + 5
6a²b² + 3ab² - a²b² - 4ab² =
5a²b² - ab²
hello!
so area of a square is calculated by this equation
s^2 = a
which means if you multiply two sides together you get the area
what you want to do now is to find a side of the square
plug in the 900 square meters
s^2 = 900
square root both sides to isoate the variable
s = 30 meters
this means that one side is 30 meters
since it is a SQUARE all four sides are equal
just multiply 30 by 4 and that will get the amount of fencing you'll need
30*4 = 1200 meters
you will need 1200 meters of fencing
WAIT
there is a possibility that one side of the house has already enclosed one side of the fence
so if that's the deal then
30*3 = 900meters
IF ONE SIDE OF THE HOUSE IS ALREADY ENLCOSING ONCE SIDE THEN YOU WILL NEED 900 meters of fencing.
Answer:
The midpoints of the given graph are ( - 1, 3 ).
Step-by-step explanation:
By the graph we have to given that the endpoints are R ( -5, 4) and S (3, 2)-
As we know that-
If a line segment AB is with endpoints ( ) and ( ) then the mid points C are-
C = ( , )
Here,
<em>R ( - 5, 4 ) and S ( 3, 2 )</em>
then the midpoints C are-
<em>C = ( , </em>
<em>C= ( - 2/2 , 6/2 )</em>
<em>C = ( -1, 3 )</em>
Hence the midpoints are ( - 1, 3 ).
2/3 girls that's mean there is 1/3 boys.
If there are 18 girls that mean half this number is the boys which is 9.
Therefore, total number is 27.
