x = 9; This problem is also true because 5x + 45 is equal to 5x + 45
Step-by-step explanation:
First you would distribute 5 into x and 9
5x + 45 = 5x + 45

Answer:
Step-by-step explanation:
eq of circle is (x-h)²+(y-k)²=r²
where (h,k) is center of circle and r is the radius.
given eq. of circle is (x+10)²+(y-4)²=100
or {x-(-10)}²+(y-4)²=10²
center is (-10,4)
and radius =10 units
