The HCF and LCM of two expressions are x and 4x^2(n+a)^2 ( x^2 - a^2) respectively. if the 1st expression is 4x(n+a)^2, find the second expression. Pleaseee fast

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 c

step-by-step explanation: i took a test with this question on it

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21
