1.3
You subtract 3.2 from 1.9 ; which gives you 1.3
Step-by-step explanation:
Root of the function, where y = 0
f(x) = x² + 2x - 1
0 = x² + 2x - 1
x² + 2x - 1 = 0
x² + 2x = 1
x² + 2x + 1 = 1 + 1
(x + 1)² = 2
x + 1 = ±√2
x = -1 ± √2
Roots → x = -1 ± √2
Answer:
Step-by-step explanation:
1. 2( 2d + 2)
2.w + 12
They are all vertical angles.
Answer: D=22
Step-by-step explanation:
this is because if multiply f by r you get D and then you do all the other rmathematics and you wind up with 22
