Sample Response:

-----------------------------------------------------------------------------------------------------------------

Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent. Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.

Let's say that someone was building a yard.

(I tired to make this all connected.)

For Part 1) He wants to put his fence around the yard. If it's a rectangle measuring 45 * 32 ft, he would have to find the perimeter of the rectangle so he could install the correct amount of fences. The perimeter is the measurement 'around' a shape.

For area (part 2), if he wanted to know how much he was able to put stuff inside, he would have to find the area of the rectangle. The area is the space occupied by a 2D shape.

Part 3: The person then wants to paint a box as a decoration. He has a small 3 * 3 *3 box. The person needs to find how much paint he needs to cover the box appropriately, or the surface area of the box. Surface area is the total measurement of the surface in a 3D figure.

Part 4: He then wants to put something in the box. He does not know how much can he fit in it, so he would have to find the volume of the box. The volume of a 3D figure is the measurement of how much it can 'fill' the shape.

Hope this helps.

On Monday, a concession stand manager ordered 985 popcorn bags and 1010 paper food trays. She splits the bags and trays evenly a

Mila [183]

Answer:

197 popcorn bags
202 food trays

Step-by-step explanation:

Since the numbers are split evenly 5 ways, each stand gets 1/5 of the total:

(985 bags)/5 = 197 bags

(1010 trays)/5 = 202 trays

Each concession stand receives 197 popcorn bags and 202 food trays.

The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the l

gulaghasi [49]

Completing the square is done as follows:

1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
9x2 +54x = 7

2. Make sure that the coefficient of the x^2 term is 1.
9(x2 + 6x) = 7

3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
9(x2 + 6x + 9) = 7 + 81

9(x+3)^2 = 88
