Mr. Hamilton decorates his U. S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 ¾ feet long. Each president's picture is 6 inches wide. 1. How many feet long is the space Mr. Hamilton wants to fill with pictures?
2. Write a math expression that explains how you got your answer for #1.

3. Convert this length to inches. Show your work.

3. If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall? How many pictures will Mr. Hamilton use?

4. Write a math expression that explains how you got your answer for #3.

5. How would your answer change if the pictures were 10 inches wide? Explain.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

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.
