Draw the figure out and you will find that AB + BC = AC. Given this, put the equations together to form x+41+x+10=22. Solve to get x=-29/2
Whatever the value of s is will be multiplied by 8 and the value of b will be multiplied by 2.
Answer with Step-by-step explanation:
We are given that
a.



b.Radius=2.58 cm
Substitute the values in the formula and 

Hence, the area of circle =20.9 square cm
c.Area of circle=1530 square cm

Hence, the radius of circle=22.07 cm
c.Area of circle of radius 15.2 cm=
Area of circle of radius 15.1 cm=

Hence, the area of circle whose radius is 15.2 cm is greater than the area of circle of radius 15.1 cm by 9.52 square cm .
Simplified :(5x+4y)(5x−4y)
=(5x+4y)(5x+−4y)
=(5x)(5x)+(5x)(−4y)+(4y)(5x)+(4y)(−4y)
=25x2−20xy+20xy−16y2
=25x2−16y2
hope this helps!
I think it's RO if it's circle O
