Answer:
C
Step-by-step explanation:
Given
A =
Substitute the given values with h = a, then
16.5 = ( multiply both sides by 2 )
33 = a(a + 8) ← distribute
33 = a² + 8a ( subtract 33 from both sides )
0 = a² + 8a - 33 ← in standard form
0 = (a + 11)(a - 3) ← in factored form
Equate each factor to zero and solve for a
a + 11 = 0 ⇒ a = - 11
a - 3 = 0 ⇒ a = 3
However, a > 0 thus a = 3
Hence the height is 3 feet
Answer:
Step-by-step explanation:
Jack makes a cuboid. If the length is <em>l</em>, the width is <em>w</em> and the height is <em>h</em>, then its volume is
The height is determined by the side of the square cut out of each corner.
Along the length of the width, the length of two sides of the square are cut.
