Question a:
f(6) = (6)² + 2(6) + 8
f(6) = 36 + 12 + 8
f(6) = 56
Question b:
f(x+4) = (x+4)² + 2(x+4) + 8
f(x+4) = x² + 8x + 16 + 2x + 8 + 8
f(x+4) = x² + 10x + 32
Question c:
f(-x) = (-x)² + 2(-x) + 8
f(-x) = x - 2x + 8
Well diameter will be the diagnol of that square..
let side of square be x, then diagonal will be root2 * x = diameter
so, raidus will be = dia/ 2
= (root2 * x ) /2
Answer:
the second option
Step-by-step explanation:
<h3>The answer is:</h3><h2>D. 5 hours</h2><h2 />
The equation should be:
(70x) - (20x) = 250
Because we have all the possible answers, we can plug one of them into x to see if it equals 250 miles.
Use an educated guess. I'm going to go with 5 because it seems reasonable.
(70 * 5) - (20 * 5) = 250
Let's check to see if it equals 250:
Therefore, the answer is D. 5 hours.
