Add and Subtract Polynomials
In the following exercises, add or subtract the polynomials.

19m-2m^2+60

Step-by-step explanation:

(8^2+12m-5)-1(2m^2-7m-1) (theres an invisible -1

64+12m-5+2m^2+7m+1 (combine the same terms)

19m-2m^2+60

x=12 units bd= 10 units

step-by-step explanation:

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
