Can 3 times the sum of r and d squared minus 2 times the sum of r and d squaredbe simplified

The expression it is simplified as the sum of r and d squared:

(r+d)^2

Step-by-step explanation:

The equation describing the line can be stated as:

3(r+d)^2-2(r+d)^2

As both terms have a repeated factor, the expression can be simplifyed by factorizing with the repeated factor (r+d)^2:

(r+d)^2.(3-2) = (r+d)^2.(1) = (r+d)^2

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).

the answer is d
