Louis's forearm measures 20 cm. 120 cm
Gregory's forearm is 125% the length of
Louis's forearm.
How much longer is Gregory's forearm
than Louis's?
A 4 cm
B 5 cm
C 16 cm
D 25 cm

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

it's d
