Simplify the expression:
x²+x/x

x² + 1

or if we suppose

x² + 1 = 0 the n we get value of x

x = ±1

Step-by-step explanation:

x²+x/x    (cancel out both x/x we get)

x² + 1

Let suppose

x²+x/x = 0

x² + 1 =0

x²=-1

taking square root on both side we get

x = ±1

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
