25 = 5*5
405 = 81*5
therefore, 25/405 = (5*5)/(81*5)=5/81
Answer:
Many answers, look below :)
Step-by-step explanation:
24.
(x)=2x^5+6x^4
Step 1. Multiply 5 by y and you get 5y
Step 2. Multiply 5 by .4(2/5)
Step 3. Your equations will look like 5y+2=-13
Step 4. Subtract 2 from its self and -13
Step 5. Your equation will be 5y=-15
Step 6. Divide 5 from both sides
Step 7. Your answer is y=-3
X^4 - 4x^3 - 9x^2 + 36x = 0
x(x^3 - 4x^2 - 9x + 36) = 0
x(x^2(x - 4) - 9(x - 4) = 0
x(x + 3)(x - 3)(x - 4) = 0
the zeroes are -3, 0, 3, 4 Answer
(pi) x 3pi = 3 pi²
pi x 3/pi = 3
