4 x 4 = 16
11 x 11 = 121
121/2 = 60.5
60.5 x 4 = 242
242 + 16 = 258
258 cm^2
A whole, is whatever/whatever.
so... he painted 4/5 of the house first..... now the whole house is 5/5, from 4/5 to 5/5 is just 1/5, so 1/5 was left for the next day.
the next day, he painted only 2/3 of what was left, what is 2/3 of 1/5? well is just their product.
It is 1 55/100. Reduced that is 1 11/20
Answer:
k = 5
Step-by-step explanation:
First three terms of an AP are 3k-1, 4k+1, 6k-2.
First term is 3k-1
For an AP,
a₂-a₁=a₃-a₂
4k+1-(3k-1)=6k-2-(4k+1)
4k+1-3k+1=6k-2-4k-1
k+2=2k-3
Separating like terms,
k-2k=-3-2
-k=-5
k = 5
So, the value of k is 5.
