1. The variable A added to the sum of the variable D and 6
2. 10 added to b multiplied by 2
10
x.25<------ 2 decimals
_____
50
+200
______
250<----move the decimal 2 times to the right
the answer is 2.5
(x-5)^2 . ( x+5)
=( x^2 - 10x + 25) . ( x+ 5)
=x^3 + 5x^2 - 10x^2 -50x + 25x + 125
= x^3 - 5x^2 -25x +125
Answer:
As we can observe,
F(1) = 567
F(2) = 189 = 567/3 = F(1)/3
F(3) = 63 = 189/3 = F(2)/3
=> F(4) = F(3)/3 = 63/3 = 21
Hope this helps!
