Answer:
3(3a - 6b + 7c )
Step-by-step explanation:
The greatest common factor of 9, 18 and 21 is 3
Factor out 3 from each term
9a - 18b + 21c
= 3(3a - 6b + 7c) ← in factored form
In triangle ABC and DEF
AC =DF, [ given ]
AB =DE, [ given ]
angle A = angle D
by SAS
ABC congruent to triangle DFE
so
BC = EF, [ CPCTC]
hence proved

<h3>Answer:</h3>
— — — — — — — — — —
<h3>Step-by-step explanation:</h3>
To find the circumference, use pi (π), a mathematical constant. Its value is approximately equal to 3.14.
— Multiply the diameter with π in order to get the circumference of a Circle.
Therefore, the circumference of the circle is 34.54 inches.
