What is the factorization of the trinomial below -x^2 + 2x + 48

For this case we must factor the following expression:

We take the sign "-" as a common factor of the expression, taking into account that:

To factor, we must find two numbers that, when multiplied, result in -48 and when added, result in -2. These numbers are -8 and +6.

Then, we factor the expression within the parenthesis as:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64
