Here is your answer for the question
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
Answer:$342
Step-by-step explanation: First we convert to yards: which gives us 14/3 yards and 20/3 yards. We multiply these to find a combined area of 280/9 yards, which we then multiply to get 280*11/3. Simplify to get 342.22 repeating, which rounds to 342.
