Answer:
AB = BC = 2√2
Step-by-step explanation:
Start by focusing on the 45 degree angle. The unknown AB is the side adjacent to this 45 degree angle, and the hypotenuse is known to be 4.
Thus,
cos 45 degrees = adj / hyp = AB / 4, or
AB = 4 cos 45 degrees = 4 (1 / √2) =
4 √2
----------- * --------- = 2√2
√2 √2
Since this is a 45-45-90 triangle, the two shorter sides are equal, and so BC = 2√2 also.

2. 114
3. .19

7. No, the associative property does not work for subtraction or division, they do not hold for the associative property. For example,
2+ (3+4) = (2+3) + 4 2- (3-4) = (2-3) – 4
2+7 = 5+4 2 + 1 = -1-4
9 = 9 3 = -5, which is not true
8. No, the commutative property does not work for subtraction or division, they will give a different result. For example,
5+6 = 6+5 5-6 ≠ 6-5
None because they will have spent it all on lawsuits
The answer is 44.4 hope that helps
Answer:
a₁ = -28
aₙ = a₁ + 12 (n-1)
Step-by-step explanation:
a₁ = -28
a₂ = -28 + 12 (2 - 1) = -16
a₃ = -28 + 12 (3 - 1) = -4
a₄ = -28 + 12 (4 - 1) = 8
aₙ = a₁ + 12 (n-1)
