Answer:
<em>a = 1 ; b = - 8 </em>
Step-by-step explanation:
x² + 2x - 7 = (x² + 2x + 1) - 1 - 7 =<u><em> (x + 1)² - 8 </em></u>
<em>a = 1 </em>
<em>b = - 8</em>
Answer:
39
Step-by-step explanation:
The angle marked 39 degrees and <2 are vertical angles and vertical angles are equal. This means that <2 = 39 degrees
From the synthetic division, f(3) = 13
-1,-2,-4
an = a1 * r^(n - 1)
a1 = first term = -1
r = common ratio = 2
so the equation would be : an = -1 * 2^(n - 1)
A - variables
B - multiplied
C - reciprocal?
D - 0
//
I'm not too sure about C. it can either be the reciprocal or the opposite.
