Complete the statements to find the limit. lim x→3 x2 + 2x − 3 x2 + 4x − 5 = The numerator can be factored as . The denominator can be factored as . The common factor of can be divided out of the numerator and denominator. The limit is . ANSWERS:
1. C
2. D
3. B
4. A

Your choices are all correct.

Numerator: x ² + 2x - 3 = (x + 3) (x - 1)

Denominator: x ² + 4x - 5 = (x + 5) (x - 1)

Common factor: x - 1

Then

lim [x → 3] (x ² + 2x - 3) / (x ² + 4x - 5)

= lim [x → 3] (x + 3) / (x + 5)

= (3 + 3) / (3 + 5)

= 6/8 = 3/4

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

it would open into a square depending on the type of envelope i’m not sure about the second part
