N = 3 i = 2
2 x 2 = 4
3 x 3 = 9
4 + 9 = 13
13 = area
Answer:
x=9
Step-by-step explanation:
Use the intersecting chord theorem:
RE*ET = UE*ES
Substitute values
21 (2x+2) = 30 (x+5)
Expand:
42x+42 = 30x + 150
transpose and simplify
42x-30x = 150 - 42
12x = 108
x = 9
Answer:
x > -1
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
From the graph we can see that our x-values span from -1 to infinity. Since -1 is open dot, it is not included in the domain:
(-1, ∞) or x > -1
Answer:
This is a single a step problem. When you subtract a positive you can flip the signs.
