It will take you 2 hours since ur going 70 mph divide the 140 mph by 70mph . Hope this helps :)
Which set of side lengths, in inches, will form a triangle? a 3.5, 7.2, and 3.0 b 10.0, 4.6, and 5.3 c 5.5, 4,9, and 10.5 d 3.2,

Answer:
The correct answer is D
Step-by-step explanation:
To form a triangle, the sum of ANY two sides of the triangle must be greater than the length of the third side.
Looking at the first: 3.5+3.0 = 6.5 < 7.2, therefore it can't form a triangle since the sum of a pair of sides is less than the third side.
Looking at the second: 4.6 + 5.3 = 9.9 < 10.0, it's the same as the first.
Looking at the third: 5.5 + 4.9 = 10.4 < 10.5, it's the same as the first and second.
Looking at the last: 3.2 + 5.9 = 9.1 > 4.5, 3.2 + 4
5 = 7.7 > 5.9 and 5.9 + 4.5 = 10.4 > 3.2. Obviously, this fulfils the condition of a triangle. Any two sides is greater than the third, therefore the correct answer is D.
Answer:
n=4
Step-by-step explanation:
divide both sides by 5 so you can isolate N
20\5 = 4
thus n = 4
Since a square's sides are all equal to each other, and the perimeter of a square is found by adding all of the sides together, we can distribute and simplify the given expression to find the answer:
4(3n+2) = 12n + 8
Using a^2-b^2 = (a-b)(a+b) you can factor the expression:
(3x^3-4y^3)(3x^3+4y^3)
