Answer:
x=6
Step-by-step explanation:
6(2x -11) 15 =21
6 × 2x = 12x
6 × -11 = -66
12x -66 + 15 = 21
-66 + 15 = -51
12x -51 = 21
-51 + 51 = 0
21 + 51 = 72
12x = 72
12x ÷ 2 = 0
72 ÷ 12 = 6
x = 6
Answer:
yoi look for what you add to the equation to make it a perfect square by dividing 6 by 2 then add 2^2 to both sides.
Answer:
volume of cylinder : πr²×h = π × 5² × 15 = 375π ≈ 1177.5 cm³

Answer:
They are not similar
Step-by-step explanation:
To determine whether the prism are similar we need to calculate their volumes
Volume of a prism = Base Area * Height
Volume of the first prism = 18ft *8 * 8ft
Volume of the first prism = 1152ft^2
Volume of the second prism = 30t * 15 * 15ft
Volume of the second prism = 6,750ft^2
Since the volumes are different, the prism are not similar.
