I would say true. Hope this helps :)
Volume is l × w × h
l = 21 in
h = 5 in
w = ?
volume = 1575 in
21 × 5 × w = 1575
105 × w = 1575
w = 1575 ÷ 105
w = 15 inches
Answer:

Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of squares on the other 2 sides, that is
x² + 12² = 13²
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x =
= 5
