Use:a^2-b^2=(a-b)(a+b)\\\\4x^2-16=4(x^2-4)=4(x^2-2^2)=\boxed{4(x-2)(x+2)}

What is 5/4, 1 8/25, and 1.3 in least to greatest
stiks02 [169]

\text{Hey there!}

\dfrac{5}{4}, 1\dfrac{8}{25}, \&\ 1.3

\text{Least}\rightarrow \text{greatest}

\dfrac{5}{4} = 1.25

1\dfrac{8}{25}=\dfrac{33}{25}= 1.32

\text{1.3 =}\dfrac{13}{10}

\text{Now, that we simplified the fraction to a decimal/ decimal to a fraction}\\\text{we can solve for the answer you're looking for!}

\boxed{\bf{Answer: \dfrac{5}{4}}\rightarrow1.3\rightarrow 1\dfrac{8}{25}}\checkmark

\text{Good luck on your assignment and enjoy your day!}

I need some help on this math problem, thanks so much

Answer:

The answer is C.

Step-by-step explanation:

Hit 'em with the Law of Sines.

sin(A)/a = sin(B)/b.

Let's say x is equal to "A", thus 5 is "a".

sin(x)/5 = sin(B)/b.

We could go for the obvious choice for "B", which would be the 90 degrees shown. To solve for the hypotenuse which will be "b", let's use the Pythagorean Theorem:

a^2 + b^2 = c^2

5^2 + 20^2 = c^2

25 + 400 = 425

sqrt(425) = about 20.6, which we can now substitute "b" with.

sin(x)/5 = sin(90)/20.6

sin(x)/5 = 1/20.6

sin(x)/5 = 0.04854...

sin(x) = 0.2427...

You can plug in sin^-1(0.2427) into your calculator, and you should end up with something like 14.047... which equates to answer choice C.
