Which three lengths could be the lengths of the sides of a triangle? 6 cm, 22 cm, 10 cm 7 cm, 25 cm, 11 cm 9 cm, 22 cm, 11 cm 10
vfiekz [6]

Answer:

All represent the three sides of the triangle.

Step-by-step explanation:

The question seeks to test your knowledge of the Triangle Inequality Theorem.

The Triangle Inequality Theorem states that the summation of any 2 sides of a triangle must be greater than the measure of the third side.

Note: This rule must be satisfied for all 3 conditions of the sides.

The answer is all can represent the three sides of the triangle.

Options (6 cm, 22 cm, 10 cm), (7 cm, 25 cm, 11 cm), (9 cm, 22 cm, 11 cm) and (10 cm, 14 cm, 23 cm) satisfies the Triangle Inequality Theorem and all represent the three sides of the triangle.

THIS IS REALLY IMPORTANT 7TH GRADE MATH:
Oksana_A [137]

Rectangle perimeter is 53 meters.

L = W + 2.3

To find the options of a perimeter, divide by 4.

= 13.25

So if this was a square, it would be 13.25 for both L and W but it's not.

Since the W has 2.3 meters more then the L, we do this.

13.25 + 2.3 = 15.55

13.25 - 2.3 = 10.95

Two of your sides equal 15.55, and the other two equal 10.95.

Hope this helps!
