Answer:
8x^15
Step-by-step explanation:
(2x5)3
=(2x5)3
=2x5*2x5*2x5
=8x15
3 ways (uncertain)
1 red or blue or green + 3 other colours
Use substitution and substitute y into the other equation. One of the equations already gives you y in terms of x, so use that and substitute it into the other equation. y = 3x - 4
Plug into the other equation: -3y = -9x + 12
-3(3x-4) = -9x + 12
-9x + 12 = -9x + 12
This is an identity. So that means that any value of x makes this equation true. So B.
Answer:
40 in^3
Step-by-step explanation:
Volume of a box is given by
V = l*w*h
V = 4*2*5
= 40 in^3
4*5-3*4
20-12
=8
Just plug in the numbers and solve. Remember that you multiply before you subtract.
