Answer:
Polynom degree: 5
Y intercept point: (0, 80)
Step-by-step explanation:
P(x)=(x+5)(x+4)²(x+1)²
When you expand, the highest power of x is 1 for first term (x+5), 2 for second term (x+4)² and again 2 for (x+1)². Overall, x⁵ will be the x term with highest power. So the degree of the polynom is 5.
The y intercept, i.e. intersection with OY axis, happens for x=0. Thus, P(0)=5×4²×1²=5×16=80. The y intercept point is (0, 80)
 
        
             
        
        
        
Answer:
Step-by-step explanation:
According to the midsegment theorem, the length of each side of the formed triangle is the half the parallel side of DEF.
<u>So the perimeter is:</u>
- P = 1/2(12 + 16 + 20) = 24
