If n = 3, what does (4n 2)(7 n) equal? How do you know? Explain.

756

Step-by-step explanation:

n = 3

(4n^2)(7n)

(4 x 3^2)(7 x 3)                            [substituting the values]

(4 x 9)(21) = 36 x 21

= 756

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).

answer: 0.1,0.85
