it could be (8x+3,72-9x²⁰¹⁷)⁸+3 or just simply x²

it is always greater or equal 0, for any x∈R

X²

If the value is positive, the result will be positive, if the value is negative, the result will be positive. Also x * x, or x^4, etc.

What is the value of X? X= B=75 C=50 A=x Thank u! Sorry i'm dumb:(

Angels on a triangle is 180°
so you add 75 and 50 which gives you 125 then u take away that by 180 to find x
and that your answer
I'm going to let you work it out since its easy question

This rational expression is nonequivalent. 5x / 25x^4 ; x^3 / 5x^15 True or false?????

It is nonequivalent. Figure it out this way. Think about what number has to be multiplied by both the numerator and the denominator of $\frac{5x}{25x^4}$ to get to $\frac{x^3}{5x^15}$ . It has to be the samee number for the one expression to be equivalent to the other. To get from 5x to x^3, we have to multiply by 1/5x^2. When we do that we get x^3. Good. Now we have to multiply the denominator by the same thing, 1/5x^2. $25x^4(\frac{1}{5}x^2)=5x^6$ . As you can see, they are not equivalent.
