Answer:
perfect square trinomial
Step-by-step explanation:
Answer:
y = 15
Step-by-step explanation:
As QR parallel to TS
QR = TS
11 = y - 4
y = 11 + 4
y = 15
Answer:
AB = 2*sqrt(5) or
AB = 4.47
Step-by-step explanation:
AB is the hypotenuse of a right triangle A and B and the corner where 2 and 4 meet.
The length of AB is governed by the Pythagorean Theorem.
AB^2 = x^2 + y^2 Substitute 2 and 4 for x and y
AB^2 = 2^2 + 4^2 Expand the right side
AB^2 = 4 + 16 Add the right side
AB^2 = 20 Take the square root of both sides
sqrt(AB^2) = sqrt(20)
Factor 20 = 2*2 *5
Rule: when taking the square root of a number the pairs can take 1 member of the pair outside the root sign and throw the other one a way.
AB = 2 * sqrt(5) One of the roots has been thrown away.
Answer:
your answer is 19,683 in^3
Step-by-step explanation:
i don't know what the heck an exercise cube is, but hey, it's the world of real world problems
volume of a cube = side length ^ 3
= 27*27*27
=19,683 in^3
