Select the expression that represents the following statement: 52 minus 4 times the difference of 13 and 7. answers 4 x (13 + 7) − 52 4 − (7 − 13) + 52 52 − 4 x (13 − 7) 52 − 4 + (13 − 7)

52 -4 X (13-7)

Step-by-step explanation:

Remember BODMAS.

We do brackets, then we do multiplications and divisions , then we do addition and subtractions.

As we want first the difference of 13 and 7, we must put them in brackets.

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
