C. The square root of 144
C^2 + 11c = 12
c^2 + 2[11/2] c = 12
[c + 11/2] ^2 - [11/2]^2 = 12
[c +11/2]^2 = 12 +[11/2]^2
[c +11/2]^2 = 12 + 121/4
[c +11/2]^2 =[48+121]/4
[c +11/2]^2 = 169/4 ----> This is the resulting equation
Solving it you get:
c + 11/2 = +/- √(169/4)
c + 11/2 = +/- 13/2
c = 13/2 - 11/2 =2/2 = 1 and
c = -13/2 - 11/2 = - 24/2 = -12
(-3+5)*2+8
2*2+8
4+8
12
The answer will be D 12
Answer:
a. 2,440 km
b.
Step-by-step explanation:
a. Diameter of Mercury =
Radius of Mercury = ½ of its diameter =
Radius of Mercury =
To convert the radius to ordinary number, multiply 2.44 by 1,000.
Radius of Mercury as an ordinary number =
b. Mass of Jupiter =
Mass of Saturn =
Difference between mass of Jupiter and mass of Saturn = (subtract 5.68 from 1.898 = 5.68. we would retain the largest exponent, which is raised to the lower of 27.)
