Answer:
Step-by-step explanation:
Let the edge of the cube be a .
Given
Volume V = a³

= 3a² x 2
= 6a²
If a = 40 cm

= 9600 cm³/s .
You would need to see the rest of the equation to plug in 7 for x. Treat it as y=equation and replace any x with 7.
Lol I just needed help with this kinda stuff...
I’m not very caught up with this stuff I feel your pain I’m very sorry if I’m wrong =/
10?
Answer:
C) 17
Step-by-step explanation:
Using the rule
A^2 + B^2 = C^2
8^2 + 15^2 = x^2
64 + 225 = x^2
x^2 = 289
x= _/-289
x = 17
Answer:
Step-by-step explanation:
As long as the indices are the same for all the radicals, you can multiply them together. Our index for each of these is 2 (square root) so we multiply them all together and put it under 1 square root sign (radical):
The largest perfect square in 150 is 25, and the 6th power on the x needs just to be rewritten in terms of an exponent of 2 to give us:
and pull out the perfect squares to get
