Answer:
C 5/13
Step-by-step explanation:
A fraction is written in reduced form if there are no common factors in the numerator and denominator. Since you know your multiplication tables, you can easily identify the common factors:
A 20 = 5·4, so 4 is a common factor 4/(4·5) = 1/5
B 6 = 2·3, 9 = 3·3, so 3 is a common factor (2·3)/(3·3) = 2/3
C 13 is not a multiple of the prime number 5, so there are no common factors. 5/13 is a reduced fraction
D 14 = 2·7, 21 = 3·7, so 7 is a common factor (2·7)/(3·7) = 2/3
Since the rectangles are similar. The ratio of their sides will be the same.
So, we can write:

Therefore, the left side of the bigger rectangle will be 12 units in length.

Answer:
x = -2
Step-by-step explanation:
Equation is given as;
4 x - 5 = 2 + 3 ( x - 3 )
Step 1: Expand the brackets
4x - 5 = 2 + 3x - 9
Step 2: Collect like terms
4x - 3x = 2 - 9 - (-5)
Step 3: Simplify
x = 2 - 9 + 5
x = -2
