Answer:
Polynomial: 2x^2-8x+3x-12
Trinomial: 2x^2-5x-12
Step-by-step explanation:
Just distribute the 2x to the x and -4 and then distribute the 3 to x and -4.
Answer:
T = 2w + 37
Step-by-step explanation:
Let T represent the total amount of videos Rachel has after w weeks
Rachel already owns 37 videos
She purchases 2 more each week
Therefore, after w weeks, the total amount of videos Rachel has can be represented by the expression:
2w + 37
Then the total after w weeks can be modeled by the equation:
T = 2w + 37
9514 1404 393
Answer:
- sin(Z) = 9/15 = 3/5
- cos(Z) = 12/15 = 4/5
Step-by-step explanation:
The hypotenuse is the longest side, XZ (15). It is opposite the right angle (Y).
The segments adjacent to Z are the ones with Z in their name: ZX and ZY. When we talk about the "side" or "leg" adjacent to Z, we are usually not interested in the hypotenuse ZX. We refer to that as the "hypotenuse." So, the side or leg "adjacent" to Z is ZY, of length 12.
The segment opposite to Z is the one that does not have Z in its name: XY.
sin(Z) = Opposite/Hypotenuse = XY/XZ = 9/15 = 3/5
cos(Z) = Adjacent/Hypotenuse = YZ/XZ = 12/15 = 4/5
Answer:
The answer is 0.268 or to be exact: 0.51768716422
Step-by-step explanation:
Since the square root of 0.268 is 0.268 itself, that is also a correct answer. If you're teacher wants you to find out the exact amount, it is 0.51768716422.
Cheers!
