Answer:
We must prove that (c+a)(c+d) = (b+c)(b+d)
- Let us use principles from mathematical induction

- a=bx , b=cx, c=dx
- a+c = b + c
- c +d = b + d
- Such that (a+c)(c+d)=(b+c)(b+d)

Each pad of paper cost 3.25. Here is how I found it.
21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25
X = 3.25

Answer:
c = <u>0.5 cm</u>
Step-by-step explanation:
Using the Sine rule in the triangle, then
= ( cross- multiply )
c × sin105° = 2 × sin15° ( divide both sides by sin105°
c = ≈ 0.5 cm ( to the nearest tenth )

Answer:
n = 11
Step-by-step explanation:
n+ 1 = 4(n-8)
<=> n + 1 = 4n - 4×8
<=> 4n - n = 1 + 4×8
<=> 3n = 33
<=> n = 11
