Answer:
1 inch.
Step-by-step explanation:
The length of a side of the new square = square root of 25 = 5 ins.
So a side of the original square = 5 - 4 = 1 inch.
Sum = -3
First no. = -15/7
Second no. = (-3) - (-15/7)
= -3 + 15/7
= -21/7 + 15/7
= (-21 + 15)/7
= -6/7
The second no. is -6/7.
Answer:
- x = 37
- DG = 22
- AG = 44
- AD = 66
Step-by-step explanation:
We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...
(x+7) = 2(x -15)
x + 7 = 2x - 30 . . . . eliminate parentheses
37 = x . . . . . . . . . . .add 30-x
Then AG = 37+7 = 44
and DG = 37-15 = 22.
Of course, AD = AG +GD = 44 +22 = 66
