The formula for N choose K is given as:
C(n, k)= ![\frac{n!}{[k!(n-k)!] }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%21%7D%7B%5Bk%21%28n-k%29%21%5D%20%20%7D)
Where,
n is the total numbers.
k is the number of the selected item.
Options C is correct.
Okay, we start with 42x^2 + 32 - 18 = 6062. To solve single-variable equations like this one, we want to isolate the x by moving all of the other numbers to the other side of the equation. We need to first subtract 32 and 18, and that equals 14. Now our problem looks like this, 42x^2 + 14 = 6062. Since 14 is the only other number on the left side, we subtract four from both sides! This gives us 42x^2 + 14 - 14 = 6062 - 14, so 42x^2 = 6062. Now to find x, we want to just have one x on the left side instead of 42, so we divide the equation by 42 to find that 42x^2/42 = 6048/42, so x = 12
All of them seem pretty correct.
Also the answer to 12 is this...
Remove unnecessary parentheses
-6x2/3p^8x3
Then reduce the #’s with the greatest common divisor 3
-6x2p^8
Calculate the product
-12p^8
And that’s your answer:)))
Answer:
212.5 m²
Explanation:
<u>Area of the figure</u>:
= area of the rectangle's + area of triangle's
= 6 × 9 + 7 × 4 + 1/2 × 13 × 7 + 1/2 × 10 × 17
= 85 + 54 + 45.5 + 28
= 212.5
