Simplify the algebraic expression 5x+3+7x+4

12x +7

Step-by-step explanation:

First determine what numbers are coefficients. Because 3 and 4 don't have a variable in them, we know they are coefficients. You can then add them together to get 7. After that, we see that 5x and 7x both share the variable x. Because they share the same variable you can add them together to get 12x. Because 12x and 7 don't have the same variable you cannot add them together. This means that 12x + 7 is your final answer.

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).

yes   because as the functions are graphed they eventually will intersect unless otherwise
