The answer is 13.5 so D. An equation for the surface area of a cube is 6a^2.
12.) AM:MN is a 2:1 ratio. BN:AM is a 1:2 ratio. MN:AB is a 4:1 ratio.
13.) three equal parts: two-thirds m. five equal parts: four-fifths m.
Answer: 4
Step-by-step explanation:
3^2 + b^2 = 5^2
9 + b^2= 25
b^2 = 16
b = ±4
3x - 5 =
divide 3 on both sides
you cancel out the 3 and when you divide the 5 by 3 you get 1.7
therefore x = 1.7
