Sorry, egyptian good at trigonometry.
So what is a) hard to prove but since, the line with the 6 is a perpendicular a= 6
What is b) you now have two angles: 45 and 90 degrees, so missing angle between a and b is also 45 degrees since 3 angles must sum to 180 degrees. since you have perpendicular height h=6, and a = 9/2 in question, and formula is 1/2 base [8 +9/2] x perpendicular height, what is the problem?

<h3>Answer:</h3>

3a² - 24ab + 48b² = 3 ( a - 4b )²

<h3>Step-by-step explanation:</h3>

<u>We will start by rewriting the given quadratic polynomial,</u>

3a² - 24ab + 48b²

<u>Taking out the common "3",</u>

=> 3 ( a² - 8ab + 16b² )

<u>Splitting the middle term i.e. " - 8ab " appropriately,</u>

=> 3 ( a² - 4ab - 4ab + 16b² )

=> 3 [ a ( a - 4b ) - 4b ( a + 4b ) ]

=> <u>3 ( a - 4b ) ( a - 4b )</u>

<u>Hence, option C is correct.</u>

2/8. 2/8 can be simplified to 1/4 if you divide by 2 in both the numerator and the denominator. Draw two pies. Make one pie cut into 8 even pieces and one cut into 4. Shade in two of the slices on the pie with 8 pieces (side by side) and shade in one on the pie that's cut into four slices (in the same spot as on the other pie). You should see how you shaded the same total area of each pie.
