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,
stealth61 [152]
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:
x = 9
Step-by-step explanation:
So lets substitute, so the equation is;
14x + 4(7) = 154
Next, lets distribute;
14x + 28 = 154
Subtract 28 from both sides
14x = 126
Divide both sides by 14
x = 9
