Answer:

If 9 students make the poster in 10 hours
Then it would take 1 student 90 hours to make 1 poster

So you'd need 15 students to make the poster in 6 hours
Which means 6 more students would need to join them

In remodeling a house an architect finds that by adding the same amount to each dimension of a 15ft by 19ft rectangular room, th
earnstyle [38]

Answer:

Step-by-step explanation:

new length=15+x

width=19+x

then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²

original area=15×19=285 ft²

then 285+98=x²+34x+285

or

x²+34x-98=0

x²+34x+17²=98+17²

(x+17)²=98+289=387

x+17=√387=3√43

x=3√43-17 ft
