To find the highest common factor (HCF) between two numbers , first to take HCF of both the numbers.

\purple {\Large\begin{array}{r | l}2&\underline{12}\\3& \underline{6}\\2&\underline{2}\\&\underline{1}\\\end{array}} \:  \:  \:  \:  \:  \:  \:  \:   \:  \: \:  \: \purple {\Large\begin{array}{r | l}2&\underline{40}\\2& \underline{20}\\5&\underline{10}\\2&\underline{2} \ \\ &\underline{1}\\\end{array}}

  • Take every common prime factor between 12 and 40

\red {\large \implies} \large \: 12 \:  =  \: 2 \:  \times  \:  3 \:  \times  \: 2 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \red {\large \implies} \large \:40 \:  =  \: 2 \:  \times  \: 2 \:  \times  \: 5 \:  \times  \: 2 \:

  • Finally, identify the factors common to each number and multiply those common factors together.

\rm\orange {\large \implies} \large \:Common \:   factors \: =  \: 2 \:  \times  \: 2

\rm\orange {\large \implies} \large \:HCF = 4

Solve. <br> | 3x + 1 | = 2
qwelly [4]
Since this is an absolute value equation, it will have two answers. For the first answer, take away the absolute value bars and solve 3x + 1 = 2. Subtract 1 from both sides to get 3x = 1 and divide each side by 3 to get x = 1/3. Now onto the second solution. This time, take away the absolute value bars and make the other side of the equation, the 2, negative, to get 3x + 1 = -2. Now solve this by subtracting 1 from each side to get 3x = -3 and divide each side to get the other answer which is x = -1. The answer is x = -1 or 1/3, hope this helps!

Two 2 1/2 inch plastic strips and two 5 1/3 inch plastic strips are used to form a rectangle. What is the perimeter of the recta
svp [43]
In this question the given information's should be closely noted. The length and width of the perimeter are already given. Based on those information's the answer to the question can be easily deduced.
Length of the rectangle = 2 1/2 inch
                                       = 5/2 inch
Width of the rectangle = 5 1/3 inch
                                         = 16/3 inch
Then
Perimeter of a rectangle = 2 ( Length + Width)
                                        = 2 [(5/2) + (16/3)]
                                         = 2 [ (45 + 32)/6]
                                         = 2 * (77/6)
                                         = 77/3 inch
                                         = 25 2/3 inch
So the perimeter of the rectangle in question is 25 2/3 inch. I hope the procedure is clear to you.
