The answer to the question
Poorly phrased question, but the general answer is 5k/(12k), where k <span>∈ Z (i.e. k is an integer).
So, 5/12 and 10/24.</span>
The Answer to your question is 4.87
Answer:
-2x^4 +10x^3 -3x^2 +5x +27
Step-by-step explanation:
a) Using the distributive property, we can eliminate parentheses:
2x^4 + 7x^3 - 3x^2 + 7 - 4x^4 + 3x^3 + 5x + 20
And using the distributive property again, we can factor pairs of like terms:
= x^4(2 -4) +x^3(7 +3) -3x^2 +5x +(7 +20)
b)
= -2x^4 +10x^3 -3x^2 +5x +27
