Answer:

2(x + 2)

Step-by-step explanation:

2x^2 + 4x

= 2x(x + 2)

2x^2 - 8

= 2(x^2 - 4)

= 2(x - 2)(x + 2)

So the HCF is 2(x + 2).

How do you multiplies fractions?
Lostsunrise [7]

Just multiply straight across. (Left to right.)

Multiply both numbers on the top then both on the bottom. Then just simplify.

An example is 1/2 x 3/4 = 3/6 then 1/2

Which of the expressions is rational
miv72 [106K]

Answer:

the third one

Step-by-step explanation:

the square root of 25 is 5. 5+2 = 7.

this is a rational number (the set of all integers and fractions).

the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.

45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.

If m and n are positive integers such that the greatest common factor of <img src="https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20n%5E
torisob [31]
The greatest common factor of m^{2}  n^{2} and m n^{3}

is
 
gcd(m*m*n*n, m*n*n*n) =m*n*n=m n^{2}

what we did, was to see how many m's and how many n's, each expression have, and then pick the smallest of each letter (factor).

the reason is that the common factor, must have enough m's and n's to divide the m's and n's of both expressions

so
45=m n^{2}
also 
45=5*9=5*3^{2}

thus, n is equal to 3
