Answer:
4900
Step-by-step explanation:
70^2 means 70*70
70*70=4900
The numbers:
1, -3, 2, -9, 3, -15, 4, -21,
are not linear.
If it was linear:
4, 3, 2, 1, -3, -9, -15, -21
39 ft²
11 ft × 3 ft = 33 ft²
2 ft × 3 ft = 6 ft²
33 ft² + 6 ft² = 39 ft²
805/38= 21 7/38
So that is 21 full payments of $38.00 and one of $7.00
