Answer:
C = 131.88 cm
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ) , then
C = 2 × 3.14 × 21 = 131.88 cm
Answer:
Choice C)
x^2 - 2x + 4 - 12/(x+2)
====================================================
Explanation:
To see how I got that answer, I have provided two attached images below. One of them shows the polynomial long division. The other shows synthetic division. Both are valid options to get to the same answer.
For each method, I used 1x^3 + 0x^2 + 0x - 4 in place of x^3 - 4 so that the proper terms could align.
Step-by-step explanation:
Triangles ABC and DEF are congruent.
The letter B is the 2nd letter in 'ABC'.
Likewise, the letter E is the 2nd letter in 'DEF'.
Therefore Angle B = Angle E.
