1 answer:

6 0

1. combining like terms you should get: -5x^4+5x^3-4x^2+17x-1

2. again combine all like terms to get: 15x^4+x^3+2x^2+15x+1

3. 5x^9+3x^8-x^7+16x^6+10x^5+x^4-5x^3+33x^2-16x

Answer:

zero goats and 120 Ilamas to get profit of $15,120

Step-by-step explanation:

Goats: G

Ilamas: l

Explicit constraints:

2G + 5l ≤ 400

100G+ 80l≤ 13,200

Implicit constraints

G≥0

I≥0

P= 84G+ 126l

See attachment for optimal area

substituting coordinats of optimal region in profit equation to get profit

When G= 132, l=0

P=84(132) + 126(0)

P=11,088

When G=0, l=120

P=84(0)+ 126(120)

P = 15120

When G= 100, l=40

P=84(100)+126(40)

P=13440
