If you are subtracting (3x^(2)+x)-(-2x^(2)+x) which of the following choices correctly adds the opposite of the second polynomial? (3x^(2)+x)+(2x^(2)+x)
(3x^(2)+x)+(2x^(2)-x)
(3x^(2)+x)-(-2x^(2)-x)
(3x^(2)+x)-(-2x^(2)-x)

i think its B

people grow faster than other people.

step-by-step explanation:

should you really be posting this isn't math boi.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

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
