This equation is in vertex form so finding the vertex is easy.
Vertex: (-1,4)
Once you find the vertex, axis of symmetry is easy.
x=-1
Then find y intercept by finding h(0).
h(0)=(0+1)^2-4=-3
Now find x intercepts by solving for x when h(x)=0.
(x+1)^2-4=0
(x+1)^2=4
x+1=±2
x=±2-1
x=1,-3
A = L * W
280 = 14 * A
A = 280 / 14
A = 20
A = 2 tens
Big rectangle: A = 280 + (14 * B)
378 =280 + 14B
14B = 378 - 280
14B = 98
B = 7
So length = 2 tens + 7 = 27
Answer
C. 2 tens + 7 = 27
Yeah because both share a point ,B
Answer:
1, 3, 4 i hope this helps ;)
Step-by-step explanation:
Subtract 6 on both sides
Multiply -2 on both sides to get "x" by itself
x = -8
