Answer:
Considering the Product and the Power rule of the Logarithms, they're both equivalent for x >0
Step-by-step explanation:
1) Considering the Product and the Power rule of the Logarithms:
2) Therefore we can say that:
Answer:
66
Step-by-step explanation:
The sum of all of the angles in a triangle is 180. So all three angles would add up to 180:
(a + 21) + 57 + (a - 30) = 180
Combine like terms:
2a + 48 = 180
2a = 132
a = 66
Recall that one of the laws of exponebt states that
Thus,
Cut the shape into shapes you know the area of and do the formula this helps
