They all 3 have no solution!
5 offices = x offices
6 hours 12 hours
quick math shows that it's 10 offices
The side length of s on the same square would be P = 4a
Answer:
1,3 and 5
Step-by-step explanation:
1) -2(7x + 1) − 5(3x2 + 3x + 2)
= -14x - 2 - 15x^2 - 15x - 10
= -15x^2 - 29x - 12
2) (5x2 − 10x + 8) − (10x2 + 19x + 20)
= 5x^2 - 10x + 8 - 10x^2 - 19x - 20
= -5x^2 -29x - 12
3) (-7x2 − 21x + 13) − (8x2 + 8x + 25)
= -7x^2 - 21x + 13 - 8x^2 - 8x - 25
= -15x^2 - 29x - 12
4) (-19x2 − 4x - 7) + (4x2 + 25x − 5)
= -15x^2 + 21x - 12
5) (-17x2 + 2x − 3) + (2x2 − 31x − 9)
= -15x^2 -29x - 12
6) -2(4x − 15) − 3(5x2 + 7x + 6)
= -8x + 30 - 15x^2 - 21x - 18
= -15x^2 - 29x + 12
