Answer:
13). -2x³ + x² + 1 14). x + 10y - 10z 15). -2x³ + x² + 1
Step-by-step explanation:
13). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² - 3 + 4
= -2x³ + x² + 1
14). (3x + 4y - 3z) - (2x - 6y + 7z)
= 3x + 4y - 3z - 2x + 6y - 7z
= 3x - 2x + 4y + 6y - 3x - 7z
= x + 10y - 10z
15). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² + 4 - 3
= -2x³ + x² + 1
Answer and explanation:
It would be a right triangle because it shows that the triangle has a 90 degree angle
If you're finding the future value: P=35,000(1-.1/1)^1. this is assuming you want to know the value of it after one year. if you want it to be more years, like two : P=35,000(1-.1/2)^2. When entered into the calculator enter it like so : 35,000(1-(.1/1))^1. when that's done you end up with $31,500. that's the machine's worth. it lost 3,500. 35,000-31500.
Answer:
Hypotenuse
Step-by-step explanation:
We have the Pythagorean Theorem.
In simple terms, the Pythagorean Theorem can be explained by one equation.

a and b being the legs while c being the hypotenuse.
Looking at the sentence, we can see that hypotenuse is our answer.
