Step-by-step explanation:
- π can be added to π to get a rational number
π + (-π) = 0
0 is a rational number
The answer is x=-7 and x=-1

Answer: b = 4 and c = 7.</h3>
===============================================
Explanation:
Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.
The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.
Plug those three values into the vertex form below
y = a(x-h)^2 + k
y = 1(x-(-2))^2 + 3
y = (x+2)^2 + 3
Then expand everything out and simplify
y = x^2+4x+4 + 3
y = x^2+4x+7
We see that b = 4 and c = 7.
Answer:
530.05
Step-by-step explanation:
you add 448 and 1.75 together, which is 449.75, then you add 449.75 and 80.3 together, which adds up to 80.3 hope this helps :)
Answer:
22.09
Step-by-step explanation:
0.5 of 44.18
of also means multiplication
so we're going to multiply 0.5 by 44.18
ie, 0.5×44.18=22.09
