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:

Step-by-step explanation:
The area of a circle is given by 
For circle B, the radius is 3 cm, it has an area of 
Circle D also has a radius of 1 cm. Its area is 
Circle P also has a radius of 1 cm and area 
The area of the shaded region is then 
The expression is -11-(-2)
Two negatives equals to a positive so,
-11+2
=-(11-2)
=-9
The distance between -11 & -2 is -9
Hope that helped :)
