Answer: you would multiply the 2 with both numbers
Step-by-step explanation:
9m x 2 = 18m
10 x 2 = 20
= 18m + 20
First you start out with your equation:
-4x = -36
Using reverse operations, divide both sides by -4. Since you're dividing a negative by a negative, you get a positive answer.
x = 9
Answer:
X could equal 1, 2, 3, 6, 9, or 18
Step-by-step explanation:
Natural numbers include all whole numbers. (1,2,3,..etc)
Sector area = 0.5 * r^2 * angle (in radians)
so:
16 pi = 0.5 * r^2 * (90*pi/180)
r^2 = 16 pi /(0.25 pi) = 64
r = 8
therefore it would be d
