Answer: 2

Explanation: The letter p stands for a number. Think of it as a placeholder or a box to put the number inside. In this case, we place 14 inside this box. We divide p over 2, so we divide 14 over 2 to get p/2 = 14/2 = 7

Then we subtract off 5 to get (p/2) - 5 = (7) - 5 = 2 which is the result of the evaluation when p = 14.

Answer:

The percentage of people who prefer football is approximately the same for the right- and left-handed groups.

Step-by-step explanation:

The bar for the right-handed group representing soccer is between 10% and 20% (below 20%) while the bar for the left-handed group representing soccer is at 20%.

Percentage of left-handed group of people who prefer soccer is higher than the right-handed group who prefer soccer. Therefore, they don't have the same percentage.

Factor the expression

DiKsa [7]

Answer:

Step-by-step explanation:

Your difference of perfect cubes formula is given as

$(a-b)(a^2+ab+b^2)$ and you have already correctly identified a as $5q^2$ and b as $r^2s$ . So we fill in the formula as follows:

$(5q^2-r^2s)((5q^2)^2+(5q^2)(r^2s)+(r^2s)^2)$ and we simplify. Remember that

$(5q^2)^2=(5)^2*(q^2)^2=25q^4$ . It's important that you remember the rules.

Simplifying then gives us

$(5q^2-r^2s)(25q^4+5q^2r^2s+r^4s^2)$

That's it, so fill it in however you need to on your end. Learn the patterns for the sum and difference of cubes and it will save you a ton of headaches...promise!!
