We can use the difference of two squares, which is:
x^2 + y^2 = (x-y)(x+y)
So,
(9m-7)(9m+7)
Hope this helps!
Answer:
this is not a right triangle
Step-by-step explanation:
^ = squared
The formula forthe Pythagorean theorem is a^+ b^ = c^
If this is a right triangle this must be true
6^ + 8^ = 14^
36 + 64 = 196
100 is not equal to 196
So this is not a right triangle
Answer:
j≥-4
Step-by-step explanation:

x = side length
Area of a square = x^2
Area of a cube = x^3
The squaring operation is directly tied to the geometric shape of a square. The naming is not a coincidence. The same can be said about the cubing exponent being connected to a 3D cube in geometry.
Notice how x^3 can be written as x^2*x. Buried inside the volume of a cube formula is the area of a square. We can effectively rewrite that second equation as
volume of a cube = (area of a square)*x
where x is the side length of the cube and square
This idea of tying together the volume and area like this will be helpful when setting up other volume formulas (eg: volume of a prism).
If you solve d = rt for t, you have t = d/r. If we have values for d and r we will fill them into that equation and divide.
. Setting that up so the meters cancel as they should looks like this:
lets us divide as we need to and at the same time cancel out the distance, leaving us time in hours. The t value then is 11.3 hours.
