An equilateral triangle has two sides given as (3x-2)cm and (18+x)cm what is the perimeter

84 cm

Step-by-step explanation:

Equilateral triangle have sides that measure the same

so

3x-2 = 18+x

Subtract x from each side

3x-2-x =18+x-x

2x-2 = 18

Add 2 to each side

2x-2+2 = 18+2

2x= 20

Divide by 2

2x/2 = 20/2

x = 10

The side measures18+x = 18+10 = 28

The perimeter is 3 times the length of one side

3*28 = 84

12 only.

Further explanation

The Problem:

The function f(x) is shown on the graph.What is f(0)?

The Process:

This problem is about determining the x-intercept and y-intercept of a function.

Intercepts are the point at which the graph intersects an axis.If the graph of a function crosses the x-axis, then the function has an x-intercept. The x-intercept(s) of a function is called the zeros or the roots of the function. From the graph we can observe that the curve has x-intercept at -2, -1, 2, and 3. It means that f(-2) = f(-1) = f(2) = f(3) = 0.If the graph of a function crosses the y-axis, then the function has a y-intercept. A function can have at most one y-intercept.From the graph, we can observe that the curve has a y-intercept at 12 only. It means that f(0) = 12.

Notes

The curve on the graph has one maximum turning point and two minimum turning points.
