4(k + 6)
Means:-
#1 Do inide the brackets first. Algebraically it means 'k' added to '6' . Algebraically we cannot take this any further, as a written statement K = ^ remains as 'k+6'.
#2 Thecoefficient '4' outside the brackets to the left , means, multiply each term inside the brackets to '4'.
Hence
4k + 24 = 4(k + 6)
NB In algebra
#1 a + b = a + b
#2 a - b = a - b
#3 a X b = ab ( The multiplication sign is NEVER shown.
#4 a divided by 'b' = a/b ( Just like a fraction.

What is the solution of -4k plus 10-k plus 2 equals 2k plus 4k plus 18?
-4k + 10 - k + 2 = 2k + 4k + 18Combine all the 'k' terms on the left side:-5k + 10 + 2 = 2k + 4k + 18Combine all the 'k' terms on the right side:-5k + 10 + 2 = 6k + 18Combine the numerical terms on the left side:-5k + 12 = 6k + 18Add 5k to each side:12 = 11k + 18Subtract 18 from each side:-6 = 11kDivide each side by 11:k = -6/11
How to prove that three points are collinear by section formula?
Let us understand this concept by taking three points A(2, 5), B(4, 6) and C (8, 8).Now, we have to prove that the points A(2, 5), B(4, 6) and C (8, 8) are Collinear.Let B divides AC in the ratiok: 1Then the coordinates of B will beBut the coordinates of B are (4, 6)Comparing we get⇒8k + 2 = 4k + 4 are 8k + 5 = 6k+ 6⇒8k - 4k = 4 - 2 are 8k - 6k= 6 - 5⇒ 4k = 2 are 2k= 1so here the value of k in both points are same so .....hope u get the answer
What is two third of six thousand dollars?
6 divided by 3 =2 2x2=4 2/3 of $6,000 is $4000.
What is 4k plus 2k equals 30?
First, factor out the k. So, k(4+2) = 30 or 6k = 30 Then divide by 6. k = 30/6 = 5 So k = 5.
What is 6- 11 equals?
