Answer:
-11
Step-by-step explanation:
As we know
area of triangle = 1/2 *height*base
32=1/2*8*base
32=4*base
8 =base
Answer:
The fourth one.
Step-by-step explanation:
I am pretty sure.
Answer:
y = -
x - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 2 ) and (x₂, y₂ ) = (3, - 4) ← 2 points on the line
m =
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 4, 2 ), then
2 =
+ c ⇒ c = 2 -
= - 
y = -
x -
← equation of line
(3+4) (40+3) (30+4)
= 7 + 47 + 34
= (7+47) +35
= 54 + 35
= 89
