Radda [10]

Answer:

$x\sqrt{1-x}+5\sqrt{1-x}$

Step-by-step explanation:

$(x+5)(\sqrt{1-x} )\\\\=\left(\sqrt{1-x}\right)\left(x+5\right)\\\\\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac\\\\a=\left(\sqrt{1-x}\right),\:b=x,\:c=5\\\\=\left(\sqrt{1-x}\right)x+\left(\sqrt{1-x}\right)\times\:5\\\\=x\left(\sqrt{1-x}\right)+5\left(\sqrt{1-x}\right)\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\\\=x\sqrt{1-x}+5\sqrt{1-x}$

put the fraction in least to greatest denomenator then put them in order please help me 1/2 3/4 1/5 7/10 please help me

DiKsa [7]

Working with fractions, you'll need to find the least common denominator (LCD). In this case, the LCD is 20.

Rewriting the four given numbers to the LCD, you would get:

10/20, 15/20, 4/20, and 14/20.

Now, you just organize it from least to greatest as:

4/20 < 10/20 < 14/20 < 15/20.

In other words, it is:

1/5 < 1/2 < 7/10 < 3/4.
