Answer:
x^3+3x^2+4x+5
Step-by-step explanation:
Ok, so what helps me solve this kind of problem is to circle, underline, or box the like terms(the ones with the same exponent and variable). Be sure to note the sign of each term when combining like terms. take it one step at a time, and work downwards starting with the highest exponent. You have -x^3 and +2x^3, which is x^3. Next, you have +2x^2 and +x^2, which is 3x^2. You should write down each of these as you go, so you should now have x^3+3x^2. Then combine the terms with no exponent but with x, which is 5x and -1x, which is +4x. You should have x^3+3x^2+4x now. Lastly, just combine the numbers 1, -1, and 5, which is 5. This gives you an answer of x^3+3x^2+4x+5.

Step-by-step explanation:
its 12 yd
A function of the form: A = P(1-r)ⁿ [OR if (1-r) <1, the function is decaying1)
1) y = 100(1-1/2)ⁿ = decay because 1-1/2 = 1/2 <1
2) y =0.1(1.25)ⁿ = growth because 1.25 >1
3) y = [(0.03)¹/²]²ⁿ = decay because 0.03¹/² = √0.03 = 0.17 <1
4) y = 426(0.98)ⁿ = decay because 0.98 <1
5) y = 2050(1/2)ⁿ = decay because 1/2 <1
Answer:
The regular hexagon ABCDEF rotates 240º counterclockwise about its center to form hexagon A′B′C′D′E′F′. Point C′ of the image coincides with point _E_ of the preimage. Point D′ of the image coincides with point _F_ of the preimage.

Answer:
D
you want to use the quadratic formula so you send the 6 over with the x² so you substact 6 on both sides and and and invisible 0x having your equation x²+0x-6 and substitute that equation into the quadratic formula
