What the function of the adenoids?

User Avatar

Asked by Wiki User

Normally the adenoids, like the palatine tonsils located on either side of the throat, help prevent infection in the surrounding tissues. However, when they become enlarged they interfere with normal breathing and sometimes with hearing. When severely enlarged, adenoids can affect normal dental development, resulting in an alteration of facial expression. Infection of the adenoids is common, the symptoms resembling those of tonsillitis, with which it is frequently associated. Surgical removal of the adenoids is advisable when enlargement and repeated infection interfere with development and health.

Is there a square root of -28?

User Avatar

Asked by Wiki User

No, there is no real number that satisfies the equation √(-28). The square root of a negative number is not defined in the real number system. However, if we extend our number system to include complex numbers, we can define a square root of -28 as √(-28) = 2√7i, where i is the imaginary unit.

What is the answer to -243 equals 90-9x?

User Avatar

Asked by Wiki User

The value of x that solves the equation -243 = 90 - 9x is x = -12.

-22 equals -p - 12?

User Avatar

Asked by Wiki User

To solve for p in this equation, we first need to add 12 to both sides of the equation to isolate the variable. This gives us -10 = -p. To solve for p, we then multiply both sides of the equation by -1, giving us p = 10.

"Another way of describing something is to use alternative words, phrases, or expressions that convey the same meaning but in a different way. This can be done by using synonyms, metaphors, or similes, or by providing a different perspective or angle on the subject matter."

What is p if 6p plus 3 equals 8p plus 6?

User Avatar

Asked by Wiki User

To find the value of p, we need to simplify the equation by combining like terms. Start by subtracting 6p from both sides of the equation, which gives us 3 = 2p + 6. Then, subtract 6 from both sides to isolate 2p. This leaves us with -3 = 2p. Finally, divide both sides by 2 to solve for p, obtaining p = -3/2 or -1.5.

Can the distributive property be used over multiplication?

User Avatar

Asked by Wiki User

The distributive property connects two different operations - for example, addition and multiplication. In this case:a(b+c) = ab + ac

Here is an example with numbers:

7(10+2) = 7x10 + 7x2

If you were thinking about other combinations of operations, I suggest you try out a few examples, whether both sides are equal or not.

What size patio set fits a 10x10 patio?

User Avatar

Asked by Wiki User

You need at least 2 and a half feet around your table to allow people to pull their chairs out comfortably and others to get around them when seated. Of course, if your guests are large, then plan for more space. A 4' table would work fine, but under most circumstances, you should be able to go up to almost 5' without issue. Good luck

What is the x intercepts and the y intercepts of f of x of the equation f of x equals x2 minus 5x plus 2?

User Avatar

Asked by Wiki User

The x-intercepts are the points where the graph of the equation intersects the x-axis. To find them, set f(x)=0 and solve for x. For the equation f(x)=x^2-5x+2, you can use factoring or the quadratic formula to find the x-intercepts.

The y-intercept is the point where the graph intersects the y-axis. To find it, substitute x = 0 into the equation f(x)=x^2-5x+2 and solve for f(x).

What is four tenths minus one fifth?

User Avatar

Asked by Wiki User

To subtract fractions, you need a common denominator. In this case, the least common denominator is 20. Four tenths is equivalent to eight twentieths, and one fifth is equivalent to four twentieths. Therefore, eight twentieths minus four twentieths equals four twentieths, which can be simplified to two fifths.

What is the value of n if 26-2n equals 8?

User Avatar

Asked by Wiki User

To find the value of n, solve the equation by isolating the variable. Subtract 8 from both sides of the equation: 26-8-2n= 8-8, which simplifies to 18-2n= 0. Next, subtract 18 from both sides: 18-18-2n= 0-18. This gives -2n= -18. To solve for n, divide both sides by -2: n= -18/-2 = 9. Therefore, the value of n is 9.

What is the coordinate measuring machine working principle?

User Avatar

Asked by Wiki User

A coordinate measuring machine (CMM) works by using a probe to measure the coordinates of objects in three-dimensional space. The machine's probe is guided over the surface of the object, collecting data points at various positions. The collected data is then used to create a digital representation of the object's dimensions and geometry.

Is the black wire on a lamp connection plus or minus?

User Avatar

Asked by Wiki User

The color of the wire does not indicate its polarity. In electrical systems, the polarity is typically designated as positive (+) and negative (-) rather than plus or minus. To determine which wire is positive or negative on a lamp connection, you would need to consult the manufacturer's instructions or use a multimeter to check the voltage.
