(2x2) + 4((3x2)/2) = 4 + 12 = 16 in^2
Formula for the circumference:
C = π d
Use the estimate of 3.14 for π: 9.42 = 3.14 d
Divide both sides by 3.14: d = 9.42 / 3.14 They have very conveniently given you a round number: d = 3 so your answer is A
Answer:
x = -11
Step-by-step explanation:
Add 9 to both sides of the equation
3 − 9 = −42
3 − 9 + 9 = −42 + 9
Simplify
Add the numbers
3 = −33
Divide both sides of the equation by the same term
3 = −33
3/3 = −33/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= −11
The answer is X=1+I sqrt 19
