Answer:
Step-by-step explanation:
The length of a diagonal of a square is , where a is the length of one side.
If the area of a square garden is 209m, we know that the side length must be m, since the area of a square is it’s side length squared.
Now we can substitute inside the formula.
When multiplying roots, the multiplication problem can simplify down to whatever is in the roots multilpied by each other.
So,
So the length of the diagonal is m.
Hope this helped!
Answer:
25
Step-by-step explanation:
divide 48 by 4 which is 25%
Look at the negative sign before the "a" term. For example, "-ax^2+bx+c" has a maximum point because of the negative sign in front of "a"(face-down parabola). This equation, "ax^2+bx+c", has a minimum point as there is no negative sign in front of "a."
Set up a proportion:
8 gallons 1 gallon
------------------ = -------------------
25.60 dollars x dollars
Then, cross multiply
8x= 25.60
x = 3.20 dollars
