Use the Pythagorean theorem (a^2 + b^2 = c^2)

7^2 + 24^2 = x^2

x^2 = 625

x = 25

The distributive property: a(b + c) = ab + ac

127 × 32 = 127 × (30 + 2) = 127 × 30 + 127 × 2 = (130 - 3) × 30 + (130 - 3) × 2

=(130)(30) - (3)(30) + (130)(2) - (3)(2) = 3900 - 90 + 260 - 6

= 3810 + 254 = 4064

127 × 32 = (130 - 3) × 32 = 130 × 32 - 3 × 32 = 130 × (30 + 2) - 96

= (130)(30) + (130)(2) - 96 = 3900 + 260 - (100 - 4) = 4160 - 100 + 4

= 4060 + 4 = 4064

Determine if the side lengths could form a triangle. Use an inequality to prove your answer.

podryga [215]

9514 1404 393

Answer:

a) no

b) yes

c) maybe (no)

Step-by-step explanation:

There are two versions of the triangle inequality. One requires ...

a + b > c

for any triple of side measures a, b, c.

The other allows ...

a + b ≥ c

which admits "triangles" that have zero height and look like line segments.

Most questions asking "do these lengths form a triangle" are concerned with the "greater than" case, and disallow the "or equal to" case.

$16+21=37\ngtr39\qquad\text{not a triangle}$

$27+34=61>58\qquad\text{could be a triangle}$

$9+29=38\ge38\qquad\text{could be a triangle if "equal to" is allowed}$
