The perimeter of a triangle is 14.4 cm and the ratio of lengths of its sides 2:3:4. Construct the triangle

Answer»

Answer:

The length of sides are

Step-by-step EXPLANATION:

It is given that the RATIO of LENGTHS of its sides 2:3:4.

Let the length of sides be 2x, 3X, 4x respectively.

Perimeter is the sum of all sides.

25.

Classify each decreasing function as having a slope that is steeper or less steep than the slope of the function represented in this graph.

Answer»

The coefficient by "x" (the slope) in slope-intercept form of linear equation (y=mx+b) INDICATE how FAST the graph is going up (if slope is positive) or down (if slope is negative).

y = (1/2)x + 2 has the least STEEP graph

y = 10X - 8 has the greatest steep graph

y = 4x - 3

y = (-3/4)x + 5
