which expression is equivalent to 7-2z-4 [z^3 - z^3+4z^2+11z+14/z+2]?

a. -4z^3+4z^2+6z+35
b. -4z^3+4z^2-10z-21
c. -18z-5
d. -18z+10

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

: )

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !

the correct answer is 1.7
