What is the simplified expression for -3(2x - y) + 2y +2(x + y)?

a. 8x + y

b. y - 4x

c. 7y - 4x

d. -4x - y

-3(2x - y) + 2y +2(x + y)

=-6x + 3y + 2y +2x +2y

=-4x +7y

=7y - 4x

answer is C. 7y - 4x

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).
