Do you have the equation needed to solve for x?
Answer:
all real number
Step-by-step explanation:
since h(x) is polynomial function
These problems really aren't hard just set them equal to each other and see if what they are saying is true. Are they equal? Do they both equal 0?
Answer:
x = 6.40 units
Step-by-step explanation:
4^2 + 5^2 = x^2
x = 6.40 units
So it's asking you to create an expression on how much you spent.
So you have already spent $30 on a DVD and $20 for a CD. And we don't know how much the videos are so that is x.
Your equation is going to be something like 30+20+5x but since it says it wants it in simplest form it's going to be 50+5x or 5x+50 either way that will be your equation answer. The reason it's that equation is because we know how much you spent already which is 50 and since you bought 5 videos of an unknown number that's how you get 5x.
50+5x
