3+8x-2y-x+1+4y
Combine all like terms and
7x+4+2y is your answer

Below is the sample response
Step-by-step explanation:
The complementary event for choosing a red marble is choosing a blue or purple. The total number of marbles is 5. The probability of choosing a red marble is 1/5, and the complement would be 4/5. That is not the same as choosing a blue marble.
A. Other crops: 35+25+20=80%
Beans: 100-80=20%
B. 300 acres×20%
=60 acres of cotton
C. Corn: 300×35%= 105 acres
Wheat: 300×25%= 75 acres
105-75= 30 more acres of corn than wheat
D. Yes, he is correct.
Corn fields+bean fields
35%+20%= 55%
(x+2)(x+6)=0
x^2 +2x+6x+12=0
Answer: x^2+8x+12=0
