What is the value of b?

b =15

Step-by-step explanation:

The sum of the angles of a triangle is 180

5b+ 4b+ 3b = 180

12b = 180

Divide by 12

12b/12 =180/12

b =15

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
