x2+x+6x2+2x−3

Question 1 options:

x ≠ -3

x ≠ -2

x ≠ -1

x ≠ 1

x ≠ -3

and

x ≠ 1

Step-by-step explanation:

the rational expression is:

a domain restriction will be when the denominator is equal to zero:

so we must find the two values of x that makes the expreesion for the denominator equal to zero.

we can do this by factoring:

and now we use the zero factor property, which means that if

we have two solutions:

and

thus, when or the denominator is zero. so in the domain we cannot have or .

So the domain restrictions are:

x ≠ -3

and

x ≠ 1

4096 bacteria

step-by-step explanation:

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
