Perimeter=4h+4
If the base is 2 more than the height, it gives us the equation:
b=h+2
The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.
This can be simplified to be 2h+4+2h or 4h+4
1. Is 46.7
2. x =57
3. 15.22
4. 14 + j = 28
5.
No graph, so cannot be precise.
But you can apply rotation 270 CCW = rotation -90 CCW
r_[90] : (x,y) -> (y,-x)
Answer:
2 - i
Step-by-step explanation:
If i in the expression f(i) is an imaginary number, then
f(i) = i^3 - 2 i^2 = -i - 2*(-1) = 2 - i
