Answer:

Step-by-step explanation:

Use distributive property. Then use exponent law.

Exponent law used here = a^{m}*a^{n}=a^{m+n}

-p^{2}(p^{2} - p - 1) = -p^{2}*p^{2} - p *(-p^{2}) - 1*(-p^{2}) \\\\= -p^{4} + p^{3}+p^{2}

Eli needs pieces of ribbon cut into strips that are 2 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression cou
Lady bird [3.3K]

3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Step-by-step explanation:

<u>DATA:</u>

Length of strips Eli need is 2.5 feet long

Length of roll of ribbon is 7.5 feet long

Number of strips that can be cut from the 7.5 feet long roll is x

<u>SOLUTION:</u>

To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.

Number of strips that can be cut = \frac{Total Length of roll}{Length of strips needed}

x = \frac{7.5}{2.5}  (expression)

x = 3 strips

Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

In the diagram below, ΔABC is inscribed in circle P. The distances from the center of circle P to each side of the triangle are
4vir4ik [10]
Supposing the sides with 6 and 8 is a right angle, you can create a new line from C and P, and find the length using the equation of a²+b²=c² or 6²+8²=c², with c equaling the radius of the circle.

After finding c, you will have to find the length from C to the midpoint of AC, using the same equation a²+b²=c². If both the lengths of C to the midpoint of AC, and A to the midpoint of AC are equal, you can do b+b to find the length of AC.

Using the same approach, you can find AB. Hope this makes sense, if not, I can clarify more.

The seventh grade class is putting on a variety show to raise money. It cost $700 to rent the banquet hall that they are going t
Doss [256]
They will need to raise at least 67 tickets because if they sold 66 tickets (15x66) they will only get $990, but if they get 67 tickets (15x67) they'll raise $1005.  The easiest way to get the answer fast is to do 1,000 divided by 15 and then see if that number equals 1000, or if you need to add one more ticket to make it at least 1,000.
