Answer:
3
- 48
Step-by-step explanation:
Given
(a + 2)(3a² + 12)(a - 2)
= (a + 2)(a - 2)(3a² + 12) ← expand the first pair of parenthesis using FOIL
=(a² - 4)(3a² + 12) ← expand using FOIL
= 3
+ 12a² - 12a² - 48 ← collect like terms
= 3
- 48

<em><u>The solution is:</u></em>

<em><u>Solution:</u></em>
We have to solve the given expression
<em><u>Given expression is:</u></em>

<em><u>Let us first convert the mixed fraction to improper fraction</u></em>
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator.
Thus we get,


<em><u>Thus the given expression becomes,</u></em>

Make the denominators same for easier calculations

<em><u>Reducing to lowest terms, we get</u></em>

<em><u>In decimal form, we get</u></em>

<em><u>Thus the solution is:</u></em>

Answer:
32°
Step-by-step explanation:
use this formula :
Now you want to get the angle be x, so the opposite side is 28 and hypotenuse is 53. Putting in the formula we get:
Sin(x) = 28/53
Sin(x)= 0.5283018868
So to find x just do Sin^-1
x = Sin^-1 (0.5283018868)
you get 31.8907918, ok so we just want the nearest degree and if we do that we get 32˚
if you put them into your calculator you will get 32˚ as your answer
