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
Answer:

Answer:
x=11, y=10
Step-by-step explanation:
x= 6+ (1/2)y
x+y=21
substitute the first equation into the second equation:
(6+ (1/2y)) + y =21
to get:
y=10
then to find x:
x+ 10 = 21
x=11
