An open box is made from a 40cm by 70cm piece of tin by cutting a square from each corner and folding up the edges. The area of the resulting base is 2176cm^2. What is the length of the sides of the squares.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
