We know the CE = 10x + 18 and DE = 7x - 1 and D is the midpoint of CE
⇒ CE = 2 * DE
⇒ 10x + 18 = 2 * (7x - 1)
⇒ 10x + 18 = 14x - 2
⇒ -4x = -20
⇒ x = 5
Now we also know that BC = 9x - 3 and AC = CE = 10x + 18
⇒ AB = AC - BC
⇒ AB = 10x + 18 - (9x - 3)
⇒ AB = x + 21
Substituting the value of x,
⇒ AB = 5 + 21
⇒ AB = 26
Hence, the value of AB is 26 units.
Answer:
x = 60
Step-by-step explanation:
For L and M to be parallel then
2x + 5 and x - 5 are same- side interior angles and sum to 180° , then
2x + 5 + x - 5 = 180 , that is
3x = 180 ( divide both sides by 3 )
x = 60

Answer:
216 cubes.
Step-by-step explanation:
The easiest way to take on this problem is to divide the side of the bigger cube by the smaller one.
Then, as in with volume, we cube this value to find the number of cubes necessary to fill such a space.
