Answer:
0.5 X 2 X 3 = 3
0.5 X 3 X 3 = 4.5
8 X 4 = 32
32 + 4.5 + 3 = 39.5 square ft
A right triangle is a triangle that has 90 degrees angle in one of its parts. You are given two points that have coordinate:
x1,y1= (-2, 4)
x2,y2= (-1,1)
To make the angle 90 degrees, there is two possible third point coordinate:
1. x1, y2 = (-2,1)
2. x2, y1= (-1,4)
The right triangle would be option C: (-2,1)
Option A and B is not a right triangle
Notice that
is the same as
. Using a graphing utility we can graph the inqueality as shown in the picture.
We can conclude that the first graph in your picture is the graph of the inequality
.
Answer:
see below
Step-by-step explanation:
a) 2(x - 1) = 4 (x + 2)
Distribute
2x-2 = 4x+8
Subtract 2x from each side
2x-2x-2 = 4x-2x +8
-2 = 2x+8
Subtract 8 from each side
-2-8 = 2x+8-8
-10=2x
Divide each side by 2
-10/2 = 2x/2
-5 =x
b)(3 - x) (x + 2) = 0
We can use the zero product property
3-x = 0 x+2= 0
3-x+x=0+x x+2-2=0-2
3=x x=-2
Answer:
1/660th of a mile per second
Step-by-step explanation:
There are 5280 feet in a mile, and he is going 8 feet per second. You do 5280/8 and you get that he goes 1/660th of a mile every second.
