Answer:
the common difference is 6.
Step-by-step explanation:
Given;
first term of an AP, a = -7
let the common difference = d
The third term is written as;
T₃ = a + 2d
The eight term is written as;
T₈ = a + 7d
The ratio of the eight term to third term = 7:1
Therefore, the common difference is 6.
we are given that ,
The combined area of two squares is 17 square meters.
Area of square=
Let the side length of smaller square be x
The size of the larger Square are four times as long as the size of the smaller square
So Area of larger square=
The combined Area is 17 square meter.
Hence the smaller square has the side length=
So the larger square has side length=
