All you have to do is put the numbers in where it asks:
3(6)(2) - -3 = 3(6)(2) + -3
= 33
Answer:
R = 4.2cm and D = 8.4cm
Step-by-step explanation:
The radius is 3.2 and the diameter is always twice much so its 8.4
Step-by-step explanation:
Draw the triangle formed by the ray.
The hypotenuse of the triangle is:
c² = a² + b²
c² = (-5)² + (2√7)²
c² = 25 + 28
c = √53
Therefore:
cos β = -5 / √53
Or, as a proper fraction:
cos β = -5√53 / 53
The least common multiple of the divisors 3 and 2 is 6. Multiplying by 6 gives you
2(4a+1) = 3a
Multiply both sides of the equation by 6.
