Answer:

-x

Step-by-step explanation:

You can distribute:

(x + 3)(x – 4)

x (x + 3) – 4(x + 3)

x² + 3x – 4x – 12

x² – x – 12

Or you can use FOIL (first, outer, inner, last).

(x + 3)(x – 4)

x² – 4x + 3x – 12

x² – x – 12

What is the sum of the first 11 terms of the arithmetic series in which a1 = 12 and d = 5?. (Points : 1). 38. . 549. . 143. . 2

Marina CMI [18]

First we will find the 11th term
an = a1 + (n-1) * d
a11 = 12 + (11 - 1) * 5
a11 = 12 + 10 * 5
a11 = 12 + 50
a11 = 62

now we use the sum formula...
Sn = (n (a1 + an)) / 2
S11 = (11 (12 + 62)) / 2
S11 = (11 (74)) / 2
S11 = 814/2
S11 = 407

What is the slope of the line ? ( question 1/4 )

yanalaym [24]

$\huge \rm༆ Answer ༄$

First Consider two points ~ (0 , -3) and (-1 , 0)

Now, use the given formula to calculate slope :

$\sf \dfrac{y2 - y1}{x2 - x1}$

$\sf \dfrac{0 - ( - 3)}{ - 1 - 0}$

$\sf \dfrac{ 0 + 3 }{ - 1}$

$\sf \dfrac{3}{ - 1}$

$\sf - 3$

Therefore, the slope of the graph is -3
