First, distribute the terms.
1(2x^3) = 2x^3
-1(x^2+11) = -x^2-11
Standard form:
2x^3 - x^2 - 11
Since there is a 3, the degree of polynomial is cubic.
 
        
             
        
        
        
From question, 
lacy learned 34 recipes in 17 weeks, 
so in 1 week she learns = 34/17 =2 recipes,
hence she learns 40 recipes in 
 = 40*2
 =80 recipes.
        
             
        
        
        
Answer: 228.01 pi and the second is near 715. 9514
Step-by-step explanation: area of a circle is pi times the radius squared. Radius is half a diameter. Half of 30.2 is 15.1. 15.1 squared is 228.01. If you use 3.14 in place of pi, and multiply that to 228.01 you get 715.9514. I think
 
        
             
        
        
        
Answer:
x = -1
Step-by-step explanation:
to find axis of symmetry, use the following equation:
x = -b/2a
in this problem, a = 3, b = 6, c = -12
x = -6/2(3)
x = -6/6
x = -1
