Answer:

A) 11°

Step-by-step explanation:

All triangles equal 180, so:

102 + 67 + x = 180

169 + x = 180

x = 11

raketka [301]

The vertex form:

$y=a(x-h)^2+k\\\\(h,\ k)-vertex$

The axis of symetry is x = h.

$y=ax^2+bx+c\to h=\dfrac{-b}{2a}$

We have

$y=2x^2+12x+16\to a=2,\ b=12,\ c=16$

Substitute:

$h=\dfrac{-12}{(2)(2)}=\dfrac{-12}{4}=-3$

<h3>Answer: x = -3</h3>

insens350 [35]

Answer:

A:∑j=15(2j−5)

Step-by-step explanation:

a = -3

d = -1 - (-3) = -1 + 3 = 2

j-th term: a + (j-1)d

-3 + (j - 1)(2)

-3 + 2j - 2

2j - 5
