Answer:
height = 78 yd
Step-by-step explanation:
<u>Formula</u>
Volume of a rectangular prism = width × length × height
Given:
- volume = 4,212 yd³
- width = 2 yd
- length = 27 yd
Substituting given values into the formula and solving for height:
⇒ 4212 = 2 × 27 × height
⇒ 4212 = 54 × height
⇒ height = 4212 ÷ 54
⇒ height = 78 yd
X-9=-13 because the 9 doesn't do with any of the others after the variable

Answer:
Step-by-step explanation:
(3x² + 4x + 4)(2x - 4)
The easiest method is probably to use long multiplication.
3x² + 4x + 4
<u>2x - 4 </u>
6x³ + 8x² + 8x
<u> - 12x² - 16x - 16</u>
6x³ - 4x² - 8x -16
Surface area of cylinder = 2πr² + 2πrh
r=14/2=7 cm
h=22 cm
Surface area of cylinder = 2*π*7² + 2π*7*22 = 98π + 308π = 406π ≈ 3.14*406 =
