Answer:
- 3
Step-by-step explanation:
let n be the number , then
3n + 4 = n - 2 ( subtract n from both sides )
2n + 4 = - 2 ( subtract 4 from both sides )
2n = - 6 ( divide both sides by 2 )
n = - 3
The number is - 3
Answer:
25
Step-by-step explanation:
'. a=3
b=8
c =2
d=5
so
3^2+3(8)+2-2(5).
9+24+2-10
=25
X≥4ft 6 in an inequality represents this situation better than an equation because there isnt really a mathematical process required in finding a certain hight limit
Answer: 49.44807
Round that however you need to. Unfortunately the rounding instructions on the screenshot are cut off, so I cannot see what that part says.
=======================================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(22) = h/132
h = 132*sin(22)
h = 49.44807
Square both sides
i = sqrt(-1)
i^2 = [ sqrt(-1) ]^2
i^2 = -1
Now multiply both sides by i
i^2 = -1
i*i^2 = i(-1)
i^3 = -i
Final Answer: -i
(this is negative i)
