Step-by-step explanation:
4x²-9
4x²+6x-6x-9
4x²+6x-6x-9
2x(2x+3)-3(2x+3)
2x(2x+3)-3(2x+3)
(2-3)(2x+3)
solution
(8x-3)(2x+3)
The answer is 21
By comparing the 4 vertices you can determine the rectangle x-length and y-length. The coordinate for the vertice is:
1,+4i
-2, +4i
-2, -3i
1, -3i
From the coordinate, you can see there are 2 x coordinate(1 and -2) and 2 y coordinate(4i and -3i) that used.
The x-length would be: 1 - (-2)= 3
The y-length would be: 4i- (-3i)= 7i
Then the area of the rectangle would be:
area= x-length * y-length= 3*7=21
Answer:
x≥72
Step-by-step explanation:
Put into an equation then solve.
x/8≥9
x8 x8
x≥72

Answer:
See below ~
Step-by-step explanation:
<u>Part A</u>
- Male elk = 105/450 = 7/30
- Female elk = 120/450 = 4/15
- Adult elk = 173/450
- Baby elk = 52/450 = 26/225
<u>Part B</u>
- Male elk = 7/30 = 0.233 = 23.3%
- Female elk = 4/15 = 0.267 = 26.7%
- Adult elk = 173/450 = 0.384 = 38.4%
- Baby elk = 26/225 = 0.116 = 11.6%
