This is nothing you need to solve, I just need a refresher about this type of math. For some reason I can't remember this right now. Can you please help? So if I have 2x^2 + 1x, isn't there technically an exponent of 1 above the 1x?
(I'm trying to factor and solve the equation: 2x^2 + x - 21 = 0, if that helps.)

Answer and Step-by-step explanation:

As goddesboi mentioned, is the same as x.

Because of this, we don't put the 1 in the exponents place, but if you do, there is nothing wrong with it. This can also be applied to 1 times a number, say for example x. We don't keep the 1 with the x because it is the same thing as saying, x, so it is easier and faster to write.

I hope this helps!

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).
