Without using a calculator, determine whether 1728 is a perfect square, perfect cube, or neither.
Take twice the number from the product of 7 and the number, the result is 32
Triangle PQR is right angle at Q. |PQ| = 3a cm and |QR| =4a cm. Determine |PR| in terms of a
A^2 + B^2=C^2 Pythagorean’s Theorem
(3a)^2 + (4a)^2 = C^2
9a^2 + 16a^2 = C^2
a^2(9+16) = C^2
a^2(25) = C^2
sqrt ((a^2(25)) = sqrt (C^2)
5a=C=|PR|
shortcut would have been to recognize a 3-4-5 triangle
Thx for helping the question is uppp
