Answer:
Select all options of x greater than or equal to 12
Step-by-step explanation:
2x + 7 <= 3x - 5
7 + 5 <= 3x - 2x
12 <= x
x >= 12
The rate of descent is <em>164.64 meters / minute
</em><em />
<em />To get this answer you just divide the total number of meters descended by the total number of minutes passed.
<em>
</em>So:<em>
</em>922.02 ÷ 5.5 = 164.64
I hope this helped!! Have an amazing day! :D

Answer:
a) 2x + 1, 4x + 7
b) L = 19 cm, W = 7 cm, A = 133 cm^2
Step-by-step explanation:
8x^2 + 18x + 7
ax^2 + bx + c
ac = 8 * 7 = 56
56 = 4 * 14
8x^2 + 18x + 7 =
= 8x^2 + 14x + 4x + 7
= 2x(4x + 7) + 1(4x + 7)
= (2x + 1)(4x + 7)
a) 2x + 1, 4x + 7
b)
2(3) + 1 = 7
4(3) + 7 = 19
A = LW = 19(7) = 133
9.
Well the first has the angles being 3x+12,x,and 90 so they have to add up to 180 degrees because it is a triangle.
3x+12+x+90 = 4x+102 = 180 solve
4x+102=180
4x=78
x=19.5
