Answer:
what number divided by 9 is 5? answer is 45
Step-by-step explanation:
Tan (45)=x/100
Put tan(45) over 1 and cross multiply to get an equation
Tan (45)•100=1x
Solve for x
Tan (45)•100=161.977
Hello from MrBillDoesMath!
Answer:
Solutions: x = +\- 5i or x = +\- sqrt(5)
Discussion:
Factor x^4 - 25:
x^4 - 25 = (x^2+5) (x^2-5) => factor x^2 - 5
x^4 - 25 = (x^2+5)(x + sqrt(5)) (x - sqrt(5)) => factor x^2 + 5
x^4 = 25 = (x +5i)(x-5i) (x + sqrt(5)) (x - sqrt(5))
Hence the solutions are
x = +\- 5i and x = +\- sqrt(5)
Thank you,

Answer:
2x³ - 3y + z²
Step-by-step explanation:
-2x³ – y – 2z² + 4x³ – 2y + 3z² Combine like terms
-2x³ + 4x³ – y – 2y – 2z² + 3z²
2x³ - 3y + z²
