Answer:
B) -12.4 + 20.6s
Step-by-step explanation:
width = (3.1s - 1.6) cm
Length = (7.2s - 4.6) cm
Perimeter of rectangle = 2* (length +width)
= 2 *(7.2s - 4.6 + 3.1s - 1.6) {add like terms}
= 2* (<u>7.2s + 3.1s</u> - 4.6 - 1.6)
= 2*( 10.3s - 6.2) {distributive property}
= 2*10.3s - 2*6.2
= 20.6s - 12.4

In binary tree there are
n ancestor at level n.
Proof :
Take P(0): At node level
0, it has no ancestors since this is a roo tnode.
Take P(1): At node level
1, it has one ancestor. The ancestor is the root, its parents which is at level
0.
Take P(K): A node level
K it has K ancestors. Its parent is at level K – 1.
Take P(K+1): At node K +
1 level have more than one ancestor than that of node at k level.
<span>Thus there are n ancestor
at level n in binary tree.</span>
Finding the slope, you get [4-(-2)]/[-1-2]=6/-3 = -2
Plugging (2,-2) and -2 into the formula y=mx+b, you get that -2=-4+b.
Therefore, b=2, making the equation y = -2x+2
