Factor the binomial 15b^3-15b

15b (b+1) (b-1)

Step-by-step explanation:

15b^3-15b

15b^2 b - 15b

15b ( b^2 - 1)

Factor b^2 ( b+1) (b - 1)

b^2 -1

b^2 -1^2

= ( b + 1 ) ( b - 1 )

Answer = 15b ( b + 1 ) ( b - 1 )

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
