The number (√5+2)/(√5-2)

Mathematics
1 answer:
goldenfox [79]3 years ago
3 0

Answer:

b:  irrational

Step-by-step explanation:

  (√5+2)

--------------  is given.

  (√5 - 2)

If we multiply numerator and denominator by (√5+2), we succeed in removing the square root symbol from the denominator:

(√5+2)(√5+2)

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

(√5+2)(√5- 2)

and the denominator becomes 5 - 2, or 3.  The denominator is now rational, but the numerator still involves the square root symbol, so overall the given number is irrational.

Can someone help me with this math problem? I have no idea where to begin.<br> Solve: |y + 8| ≥ 3
lorasvet [3.4K]
Since y+8 is positive, you don't have to find the absolute value since the absolute value is y+8. all you have to do is find a number that makes the statement true for y. the symbol between next to the 3 asks for a number that is greater or equal to 3. So your answer would be

≥-5

If you wanted to use the numeric key pad to divide 100 by 2, you would type _____.
Nookie1986 [14]
If you wanted to use the numeric key pad to divide 100 by 2, you would type D. 100/2. This is because the / sign is used for division on like a calculator or on the web page. It also can stand for a fraction but here it would stand for dividing. 100/2 = 100 ÷ 2.

Given
f(x)= -3x - 5
g(x)= 4x - 2

Find
(f - g)(x)
substitute the f and g values in (f - g)

(f - g)(x)= -3x - 5 - (4x - 2)
change the signs in parentheses because there is a negative sign in front of the parentheses

(f - g)(x)= -3x - 5 - 4x + 2
combine like terms

(f - g)(x)= -7x - 3


ANSWER: (f - g)(x)= -7x - 3

Hope this helps! :)

Step-by-step explanation:

To find the cubic feet of a square or rectangular shape, measure the length, width and height of the object in feet or inches. Once you have these three numbers, multiply them together to get the volume. If you measured in inches, divide your answer by 1728 to convert the measurement to feet.
